1. The Illusionist
Reason: the ending of this movie was beautiful, happy, and best of all, totally unpredictable. When was the last time you saw a movie that had an ending that was beautiful, happy, and unpredictable? It almost never happens. Savor it.
2. Rocky (spoilers)
Reason: This movie could have easily gone cheesy-Hollywood and made Rocky won, but instead they made it more realistic and gritty, and yet also created one of the most moving and inspirational endings of all time. This is the only movie that has ever made me want to get up and go for a run. Ever.
3. The Sixth Sense (spoilers, we all know what happens though right?)
Reason: Right off the bat let me say I do not like this movie. I'm not a big fan of Bruce Willis (or I should say, not a fan of Bruce Willis in lead roles) and while the plot of this film is riddled with holes and cheap scare tricks-it's still thought provoking. Any ending that actually creates cliches I can respect, which is why this made my list. Show me someone who claims to have predicted he was dead the whole time, and I'll show you a liar.
Others that could have made this list...Lucky Number Slevin, Unbreakable, Psycho, Fargo, Fight Club, Matchstick Men.
