I meant the movie, of course...
Yes Imdb's ratings are dangereous and were able, a while ago, to make me miss good movies.
I use a combination of ratings and sources.
The magazine "Sight & Sound" is very good.
Also the French magazine "Brazil" is a good source.
One rating system that works surprisingly well for me is the rotten tomatoes one, and that's why I requested a script one that could gather these ratings.
