I walked out of Hidalgo, I think. What a piece of shit that was. Viggo Mortensen rides around the desert on a horse and then it rips off The Mummy or something. Fuck you, Viggo Mortensen.
I won some free movie passes from a paper once (I didn't even enter the competition, my dad worked there and fixed it) and took a bunch of people to see Van Helsing. Most of us walked out after an hour but I ended up going back in because my then-girlfriend wanted to stay and watch the rest. And yet it was another year before we broke up. She's probably dead now though so I win.
