Just curious what some of people's favorite plot twists have been.
Oldboy's (SPOILER] daughter.
The Steven Soderbergh film Side Effects. I love those twists in a story that say "everything you saw with your own eyes might just be a complete lie".
^ Both great twists (and damn the Oldboy remake to hell). I'd say 'Fight Club,' not so much for the twist itself (which has been copies SO MANY TIMES), but for the implications of what it represents about being a human being.
