Worst movie ending ever?

[TallSilhouette]

Dunno about worst ever, but I hate completely contrived twist endings that do absolutely nothing to earn their surprise; no setup, no foreshadowing, and God forbid it make any actual logical sense. Shyamalan is of course famous for this, but another movie I saw that comes to mind is The Tourist. Haven't seen it but I heard Now You See Me falls in this boat, too.
