i dont know why all saying enderman is a refference to weeping angels. i rather say that the enderman was inspired by the "slenderman" you see ENDERMAN ... slENDERMAN, it would make more sense. scince they look the same. (BTW, i think the silence from doctor who are ispired by the Slenderman too.)
This is what Notch was going to put in the game instead of Endermen, thats why people are comparing the two. I think.
