FAQ
What happens when a movie cannot be matched?
External ratings appear only when titles and movie metadata produce a reliable match. When the match is uncertain, nothing is added and the Douban page remains unchanged.
Does it replace Douban ratings?
No. It keeps Douban as the main page and adds IMDb or Rotten Tomatoes context so you can compare rating systems in place.
When are ratings updated?
Found ratings are cached in your browser for 7 days; unmatched results are retried after 1 day. After the cache expires, the next visit fetches fresh source data.
