I would have walked out of Titanic if I had been able to. As it was I was trapped in the middle of a row in a crowded cinema & unable to move.

Titanic is still up there as the worst movie I've ever seen, but has been joined recently by Twilight. Though at least the latter was a borrowed DVD so I hadn't forked out any money.

But I have to say I wouldn't have dreamed of asking for my money back. I think it's my problem if I didn't like it. Obviously many, many people loved both those films! However, i would ask for my money back if there were technical problems.
