LOTS!
Titanic - dumb ass. three hours long and the last hour is all water. just when you're desperate for the loo. i gave up and went outside to smoke cigarettes and got chatted up by two aussie blokes using the laundrette next door to the cinema.
The Piano - what was the point?
Breaking the Waves - disturbing.
American Beauty - so bad, I left to go to the bar in the mall w/one of my mates whilst we left the others to their fate.
I hired 'Notting Hill', b/c I knew it was gonna be shite but it was hire one, get one free down at Blockbuster.
I turned it off b/c all those stereotypes about the English pissed me off.
Three Kings - another one I turned off.
Oh, Brother, Where Art Thou? - walked out
The Blair Witch Project - should come w/a warning if you've got a delicate stomach or are prone to motion sickness. I was routing for the witch as the end.
