14. Jack freezes to death in Titanic (1997)
Would James Cameron's record-setting romantic epic endure if Jack (Leonardo DiCaprio) hadn't sacrificed himself and frozen to death in the ocean to keep Rose (Kate Winslet) alive on a floating wall panel (one that we're supposed to believe can't also support the 85 lbs. that is Leo's soaking wet body)? We just can't help feeling his life could have been saved by two words: Scoot over?
