What you need before you start

Pick the theme before gathering titles. A theme can be a subject, a region, a decade, or a style of documentary. Write the theme in one or two sentences so the list stays focused.

Decide where the list will live. It can be a note on a phone, a shared document, or a list inside a media app. The place should be easy to open and easy to add to.

Gather the titles you already know fit the theme. A short starting list of a few titles is enough to begin. Add more as you watch or as friends suggest titles.

Decide who else will see the list. If friends or family will add titles, agree on what counts as a fit for the theme so the list does not drift.

If the list will feed into a media library, have the matching app ready. Radarr adds movies to a media library and Sonarr adds shows to one. Have the matching app ready if the list is meant to become a watch queue.

Keep the rules simple. A themed list works best when anyone can tell at a glance whether a title belongs.

Step by step

Write the theme in one or two sentences. Name the subject, the region, the decade, or the style that the list will follow.

List the titles you already know fit the theme. A short starting list is enough. Add a line for each title with the year and a short note on why it fits.

Pick one place to keep the list. It can be a note, a shared document, or a list inside a media app. Tell anyone who will add titles to use only that place.

Add titles as you find them. When a new title fits the theme, add it to the list with the year and a short note. Skip titles that only partly fit.

Review the list once a month. Remove titles that no longer fit the theme and add any that were missed. Keep the list short enough that it can be read in one sitting.

Share the list with the people who will use it. Send the link or the note, with two lines on how to add a title and how to flag one that does not fit.

If the list feeds into a media library, move the titles into the matching app. Radarr adds movies to a media library and Sonarr adds shows to one. Add the titles there so they can be watched or queued.

After the first month, ask the people who use the list what confused them. Edit the theme note or the rules to fix those points.

Tools that can do it

Watcharr is made by the team that publishes this site. You paste one public IMDb list and get one link for Radarr with the movies and one for Sonarr with the shows. ^[1] Each link acts like a small Radarr or Sonarr server, so Radarr checks it every 15 minutes and Sonarr every 5. ^[1] A bookmark you click inside Radarr or Sonarr adds the list for you, using that app's API key without sending it anywhere else. ^[1] It accepts any public IMDb watchlist or list from the desktop site, the phone site or IMDb's other-language pages. ^[1] The links are built from the IMDb list's id, so the same list always gives the same two links. ^[1] It looks up TheTVDB ids through TVMaze and TMDB, leaves out shows it can't match, and tells you which ones it skipped. ^[1] The page shows the list's covers in a row, each opening TMDB's plot, genres, rating, backdrop and trailer. ^[1] If you sign in, it re-reads your list about every 15 minutes and warns you when a list fails three reads in a row. ^[1] Signed-in users can combine several IMDb lists into one Radarr link and one Sonarr link for the whole household, and a title that is on two lists is added only once. ^[1] If a read of the list fails, the links keep serving the last list that loaded correctly. ^[1] Watcharr runs as one Cloudflare app with a Cloudflare database, plus a GitHub job that reads IMDb. ^[1] Its code is available to read under the PolyForm Noncommercial 1.0.0 licence; older versions remain under MIT. ^[1] You paste, copy and browse from any screen in the web app; the one-click sticker shows on bigger screens. ^[1] The hosted version needs nothing to install and no account. ^[1] Commercial use is not licensed, and no commercial licence is for sale. ^[1]

A shared document is a simple option. People add documentary titles to the chosen shared list. The cost is not published.

A note on a phone or a desktop is another option. The keeper writes the themed list in a note and shares it with the people who will use it. The cost is not published.

Common mistakes to avoid

Avoid picking a theme that is too broad. A list that covers every documentary ever made will not stay focused. Write the theme in one or two sentences so the list has a clear edge.

Avoid adding titles without a short note. A note on why a title fits the theme helps the next person decide whether to keep it or remove it.

Avoid letting the list grow without review. A themed list that is not checked once a month can drift away from the theme. Remove titles that no longer fit and add any that were missed.

Avoid sharing the list without rules. Tell the people who will add titles what counts as a fit for the theme and where to flag a title that does not fit.

Avoid choosing a tool without checking how it handles the list. Before choosing a tool, check how it reads the list, how it updates it, and how titles move into the media library workflow.
