Whenever I went to see Marvel's The Avengers there was a guy letting out the biggest laugh any time anything that was meant to be funny happened, it was like having a terrible laugh track with the movie. Same kind of thing when I saw Despicable Me 2, there were some teens and they were laughing way too hard a jokes meant for very some children...I really hope they were just really stoned.
The last time I went to a movie and there was just a group of people talking, and not even about the movie, just like they paid to sit in a theatre to have a conversation, was Open Range.
