Already mentioned by others The Matrix, Crash and Fight Club. I watched them all the way through though.

Some personal 30-60 minute wonders (the point at which I couldn't stand them anymore and had to turn off would be Dances with Wolves, Ghandi, Lost in Translation, Crouching Tiger Hidden Dragon, Snatch, Amelie, Lock Stock and Two Smoking Barrels, Garden State just off the top of my head I'm sure there are many more.
