When the ending of a book, play tv series or movie has such a dramatic and unforseen twist that it is an ending worthy of the director M. Knight Shyamalan (The Sixth Sense, The Happening, Unbreakable, After Earth).
Derp 1: Man I just watched the last episode of Lost...I don't even... I just did not see that coming at all.
Derp 2: Yeah I saw it too. It was a Shyamalending if ever I saw one.
