Well I'm a movie LOVER , and really try to go along for the ride, disengage the critic for 2-3 hrs
and get my $7 worth ...... I
I've only walked out of one movie, but forgot which.

Terminators 2 was, IMO absolute trash , (if one is over age 12). I was hoping it'd get better and shoulda just left.
If Meghan Fox wasn't in it, I'd have passed on it , for sure.

Other than the Exorcist, it's the only film I truly regret seeing, but for different reasons, had nightmares for weeks after that one.

Hated the ending of "No Country For Old Men" ... as a writer I feel they betrayed the audience, with no real ending. A cardinal sin for screenwriters. Brilliant story-acting with no resolution.
