This time it’s not too big. Thor: Ragnarok has a lot of human appeal and a spirit of silliness that it never loses and yet always carefully manages, so that the silliness remains an ongoing source of delight without ever undercutting the impact of the action.

It’s not hard to imagine a young audience completely losing their minds over the thrills and action of Thor: Ragnarok, and then loving it all over again when they realize how funny it is.

This movie is so colorful and zippy and packed with outlandish supporting characters, that Hemsworth’s job is relatively easy. He just needs to look great, kick ass, nail the one-liners, and ride off into the sunset (or Avengers: Infinity War, whichever comes first). Thor: Ragnarok is sort of like a giant flatscreen TV hanging on a wall with an enormous hole in the middle of it. The TV is beautiful, but it doesn’t fix the hole. It just covers it up.
