The problem with reviewing a new Marvel movie is the same as the problem with reviewing a new Dresden Files or Vlad Taltos book: too much accumulated past knowledge is required.That is, the only way to come close to getting a coherent thought out of me is if I assume you are aware of everything that has come before. Otherwise, I’m bound to spoil for previous movies.
For example, Thor: Ragnarok, which is not only the third Thor movie, it’s in the high teens for total Marvel Cinematic Universe movies overall. And okay, they don’t all of them interweave so tightly that you would need all the movies under your belt, but it’s still something like five or six, just to cover all the returning characters.
So, screw it, I’m doing that spoil for previous movies thing. See, the first Thor movie was about learning how to be worthy. Thor starts off as a bro, and needs to be a hero instead. Cool. The second one was about family (and also a little bit about the eventual Infinity War that we’re not quite to, yet, but that’s plot, and I’m talking theme here). Like, Loki is still a bad guy, or at least a mischief guy, but the brothers are brothers again and don’t have to spend so much energy on hating each other. It was nice!
This third movie is about becoming an adult. Training wheels are off, the end of
the world Asgard is at hand, and Thor (and whoever else is willing to side with him; telling you in advance would be, well, telling) has to figure everything out for himself. Which, not bad for a dude who was a bro like six years ago. I mean, assuming he succeeds. But trying is also pretty cool. Bro Thor from 2011 would not have even tried to do anything except maybe tug on Odin’s arm, unless it was to charge forward blindly and get himself killed in the first thirty seconds.
So, that’s what the movie is. Remaining things to know are that it was almost more comedy than action movie; that it has my personal favorite use of a Led Zeppelin song; that of course it was good, although at the same time it’s hard to know how to trust my opinion here anymore; and that… no, I take it back, anything else I could possibly say would definitely be spoilers. Go see it!
 I mean, I didn’t like the Inhumans series, so at least I know there’s a bottom to this well of good faith.
