To have to put up with the shit that goes on at movie theatres, and the kick-ass cost of going to see one, every movie I go to should be 2.5 hours long. Minimum. I must say though, there were no negative experiences from my most recent Indiana Jones outing in Capitola, for what that is worth.
I have seen (1) movies in the past 2 years I think, so I am totally a person with a right to an opinion on the subject.
