How horror fans can add unseen films to a download queue in 2026

Build a horror watch queue by checking viewing history, choosing unseen films, and reviewing how a shortlist reaches the download queue.

VLClean is published by the makers of Askarr and Watcharr, which are compared here alongside other tools.

Start with a horror shortlist, remove films already watched, and check each remaining title before adding it to the download queue. Choose between entering titles manually, reviewing a shared checklist, or using a list tool after checking how it passes titles to the apps that manage the queue.

Option	Method	What to check
Manual queue entry	Review a written shortlist and enter approved films individually.	Check title matches and existing queue entries before submitting.
Shared checklist	Collect suggestions and mark films ready for manual review.	Check sharing controls and agree who approves titles.
Watcharr	Paste a public IMDb list to get a movie link for Radarr and a show link for Sonarr. ^[1]	Check how viewing history and approval settings will be handled in the overall workflow.

What you need before you start

Prepare the titles or types of content that are allowed, so people know what kinds of requests fit the server. Keep the request rules simple, such as whether people can ask for any horror film or only certain kinds of horror.

Gather a shortlist and whatever record helps distinguish watched films from unseen ones. That might be a personal viewing log or notes kept by the household. Decide whether unseen means nobody has watched the film or the person choosing the next film has not watched it.

Have the current library available for comparison. Treat already watched, already available, and already queued as separate checks. A film can be unseen without needing another download, so review those details before passing the shortlist along.

Decide who will review titles before anything is added. For a shared queue, agree on how to handle a film that some people have seen and others have not. Choose where the approved shortlist will live, and keep enough title information to distinguish a remake from an earlier film with the same name.

Step by step

Choose a manageable shortlist. Start with the horror films under consideration rather than every title collected over time. Write down the title and release year when needed to distinguish similar names. Keep uncertain entries aside until the intended film is clear.

Check what unseen means for this queue. Compare the shortlist with the viewing record chosen for the household. Remove films that do not meet the agreed rule. If viewing history is incomplete, mark uncertain titles for review rather than treating a missing entry as proof that nobody has watched them.

Compare the remaining films with the library. Look for titles already available to watch, including alternate editions or differently named entries. Move those to a viewing shortlist if appropriate. Keep the download shortlist focused on films that still need to be obtained.

Review the existing queue. Check whether any shortlisted film is already waiting there. Keep a note of unresolved titles so the next review does not start from memory. If people maintain separate shortlists, compare them before submitting the same film again.

Choose how titles will reach the queue. Use manual entry for a shortlist that needs individual review, or assess a list tool against the current workflow. Before connecting anything, check how titles are selected, what happens after a list changes, and which settings control whether a film proceeds toward downloading.

Review each intended match. Confirm that the selected title is the film requested, especially where remakes, sequels, or similar names could cause confusion. Check the desired language and edition where those details matter. Leave ambiguous entries out until they can be resolved.

Pass along the approved shortlist. Follow the chosen method and inspect the receiving app afterward. Confirm that the intended films appear where expected before relying on the process for a larger list. Keep the reviewed shortlist available while checking the result.

Maintain the shortlist after viewing. Update the viewing record when a film has been watched, and review old entries before submitting them again. Tell anyone sharing the queue where to record changes and who handles uncertain titles.

Tools that can do it

Choose where titles will be reviewed and how approved films will move into the existing workflow. Compare these options against the amount of checking needed before a title is submitted.

Manual queue entry. Keep a written shortlist beside the app used to manage downloads, then search for and review each approved film there. Before choosing this method, check how that app identifies films, shows existing entries, and asks for approval. Keep title notes until the receiving entry has been checked.

A shared checklist followed by manual entry. Give the household a place to suggest horror films, record viewing history, and mark titles ready for review. Choose fields that make the decision clear, such as the intended film and whether it is already available. Check the chosen checklist's sharing controls before inviting other people.

Watcharr. Paste a public IMDb list to get a link containing its movies for Radarr and a separate link containing its shows for Sonarr. ^[1]

No other named tool is included because no source facts about other tools were provided. Before choosing a tool, check how it handles title matches, viewing history, updates, and the way selected films move into the library workflow.

Watcharr

Watcharr is made by the team that publishes this site.

The hosted version needs nothing to install and no account. ^[1] It accepts any public IMDb watchlist or list from the desktop site, the phone site, or IMDb's other-language pages. ^[1] The same IMDb list always gives the same pair of links. ^[1]

A bookmark you click inside Radarr or Sonarr adds the list for you. ^[1] Radarr checks the Watcharr link every 15 minutes, and Sonarr checks it every 5 minutes. ^[1]

When signed in, Watcharr re-reads the list about every 15 minutes and warns when a list fails three reads in a row. ^[1] If a read of the list fails, the links keep serving the last list that loaded correctly. ^[1]

Signed-in users can combine several IMDb lists into a shared pair of links for the household, with a title appearing only once even when it belongs to several lists. ^[1] Keep the watched-film review as a separate step when preparing the horror shortlist.

Common mistakes to avoid

Avoid treating every saved horror film as an approved download. Review the shortlist against viewing history, the available library, and the existing queue before passing it along.

Avoid choosing a tool without checking how it fits the current way movies are added to the library. The process should be clear for both the people suggesting titles and the person managing the server.

Avoid assuming that matching names identify the intended film. Check remakes, alternate titles, and similar names before accepting a match. Preserve enough information in the shortlist to resolve uncertainty later.

Avoid forgetting to review the list after setup. Old suggestions can remain relevant, but they still need checking against what has since been watched or obtained.

Things to check before you choose:

Can watched films be excluded using the viewing record being maintained?
Does adding a title require approval before downloading begins?
What happens when a title is removed from the source list?
Where can uncertain matches be reviewed?
What information and access does the chosen method require?

Frequently asked questions

Can Watcharr turn a public IMDb horror list into a Radarr list?

Paste a public IMDb list into Watcharr to get a movie link for Radarr and a separate show link for Sonarr. ^[1] Before submitting the horror shortlist, compare its films with viewing history and the current library. Confirm how the receiving app handles approval and downloading before relying on the list for ongoing additions.

Does Watcharr require an account or installation?

The hosted version of Watcharr needs nothing to install and no account. ^[1] Signed-in users can combine several IMDb lists into a shared pair of links, with duplicate titles included only once. ^[1] Decide whether to maintain a shared shortlist or separate suggestions, and agree who checks those suggestions against the household's viewing record.
