I had more difficulty to find a second topic and achieve my goal. Then I remembered being asked about French sites for interesting DVDs or bargains. I think I advised Artus, Le chat qui Fume, Malavida and a few others. Of course, there's always the problem of languages and subtitles but it can be checked easily. Personally I'm still looking for many movies. For instance, decent and affordable copies of Seven Women or Cronaca familiare, with French or English subtitles, just to give 2 examples. Up to you now! (Mission accomplished as to the bloody ads!)
@lezard I wasn't talking about online-watching. If you watch a movie or series from DVD via VLC it is possible to add subtitle-files stored on your machine downloaded from the site I've mentioned above.
