We just got back from watching Thor: Ragnarok.
It was great! No, it's not high art, but it's a great popcorn flick and a good movie to see in the theater. It was funny as hell, visually engaging, and entertaining. I'll watch it again once it hits Redbox or Netflix.
If you're not familiar with the current Marvel universe, you might get lost now and then. Watching the first Avengers movie and *maybe* Dr Strange (his part is short in this movie, but you might not get his power and significance if you've not watched the movie) will give you enough background to understand some of the comments, references, or just sly looks. :)
