in addition to the whole time travel deus ex machina, i didn't like that everyone was all "hold the door, hodor" a thousand times when he held the door. like what an bad person thing to do. trick/force some Fake Sugar Dick (WARNING, NOT THE REAL SUGAR DICK!) giant into killing himself to buy you a couple of minutes. the child that blew up, the ravenman and the wolf all willingly sacrificed themselves and no one was egging them on. but with hodor it was all, "come on hodor, hold the door. do it, big man, hold the rough ridin' door." they weren't even guilty or conflicted about it.
