Ditto "Primal Fear", "Shattered" and "Dirty Rotten Scoundrels."
I also have to include "Spider-Man", despite the fact that immediately after we saw it DW Lauri said she "had issues" with the ending because . That last scene, in the cemetery -- where Peter kisses Mary Jane and walks away with them "as friends", even though she's admitting that she loves him and he's always loved her but he doesn't want to subject her to any more danger, that look on her face after the kiss (and you wonder, does she know?), and that voice over where he says "I will never forget these words, "with great power comes great responsibility." This is my gift, my curse. Who am I? I'm Spider-Man" -- was perfect. Personally, I would have been disappointed if it had a happy tidy ending, because that's not Spider-Man.
