I fell asleep in this one - just before the "exciting" ending. doh!!
Worst film though was Batman Forever (?) - the one with Mr Freeze in it. I went with 2 mates and when it was over we discovered we'd all wanted to leave after 30 mins but hadn't said anything cos we thought everyone else was enjoying it!!
A close second was The Mummy; the only film I have walked out of. It was an utter disgrace.
