I can pretty much sum up this movie in one word, but since this is a blog post, I'd probably better write a bit more than that!
And obligatory note for people Google searching "Thor Ragnarok curse words" and ending up here, there are a few in the movie, but not much.
So that one word? FUN!
The previous two Thor movies were kind of the mostly forgettable duds of the MCU. Kenneth Branagh made a solid movie, but the attempts at gravitas felt forced in some places. I really don't remember much about the second movie except for a cell phone and shoe falling through a dimensional portal and Loki's illusions to trick the dark elf at the end.
This time, Marvel pulled out all the stops and just made a rollercoaster movie. It's not deep. It's not some wonderful study of the human condition. It doesn't have any Oscar level performances. But it's got Dr. Strange being kind of a dick to Thor, Loki scheming as only he can, Thor and the Hulk smashing things, and a lot of humor.
Plus...spoiler alert...just as in the Norse mythology, Asgard is destroyed. How it gets destroyed is actually kind of clever.
And the obligatory after credits scenes...one is apparently a set-up for Avengers: Infinity War, the other is just a fun little extra. My son was a bit disappointed that there wasn't one for Black Panther, but I guess there was already the one at the end of Civil War so Marvel is thinking ahead.
Anyway, if you're in the mood for a fun popcorn action flick with sci-fantasy trappings, this is a good one. I'd rate it up there with the Guardians of the Galaxy movies for fun cinema.
