1) The Jungle Book (1994)
My entire family walked out of this movie about 20 minutes in. Honestly, I was too young to remember everyone's reasons. I know the wolves getting hurt bothered me but none of us were having this. We left the theater and walked into another.
2) The Devil's Rejects
This movie was absolute trash. Mind you, Rob Zombie is a shitty screenwriter to begin with and the film's predecessor, House of a 1000 Corpses wasn't good either. Its hyper-sexual because that's how Zombie thinks people actually talk, and he framed his villains as the heroes only they are so dull and vile that I struggle to understand why I'm supposed to be interested in them in the first place.
3) The Book of Eli
This movie I technically left and came back in. I was so bored during it that I excused myself to the "rest room" and by rest room I mean "Went to sit in The Lovely Bones for a while"
