The Trakt alternative
Drop Trakt's data-export zip in whole. History, watchlist, and ratings come across, riding the tmdb and imdb ids when the export carries them and plain title-and-year when it doesn't.
The Simkl alternative
The CSV backup as it stands: completed arrives watched and dated, the rest queues up.
The IMDb alternative
Ratings and watchlists both, matched by tt-id. Verdicts carry over exactly, dates into the diary.
The Serializd alternative
Serializd never shipped an export, but the community built one, and its JSON drops straight in: shows, ratings, and diary dates find their shelves.
The long tail
MovieLens ratings arrive with their stars doubled onto the 10-point scale. iCheckMovies' checked and watchlist exports come through on their IMDb ids. Criticker's 0-to-100 scores step down to tenths. TMDB's own list and ratings CSVs match by id, no lookup needed. Even your Netflix viewing history counts: films land watched with their dates, and series land in your queue to pick back up properly.
Anything with a title column
No recognized dialect? Any CSV or JSON that carries titles gets a best effort: year, type, rating, watch dates, and tmdb or imdb ids all ride along when they're present. Files are read in your browser; only the matched titles reach your library. Anything already tracked here is kept. Imports never overwrite.
What you're moving into
Queuebrick is a fast, quiet place to keep your film and TV life: search anything, queue what you want to watch, check off seasons as you go, and rank your favorites. Free, no ads, on the web and on iPhone. Coming from Letterboxd or TV Time instead? Those have their own doors and their own page. Your data stays yours: everything you import can be exported back out any time.
