They're mostly movies that grew up with, the type of movie that when ever I think of good childhood memories spring to mind.
Space Jam, Good Burger, Jurassic Park 2 and Independence Day are the only ones that really come to mind right now. All of them are pretty awful, but damn it I will gladly sit down and watch them all.
For something more recent: Shoot-em up, basically everytime someone other then Clive Owen spoke was a little terrible, but god damn I love it. This should be part of a class on how to do brainless action right, I mean even if you hated the movie and were barely paying attention you probaby remember half this nonsense.
