I looove the Thor franchise and Ragnarok was amazing. This one was as epic. In a different way though. I always love the humor, and Natalie Portman as other Thor. Epic.
Anyway, I have noticed some people didn't like it and have actually noticed one thing about all the movies. They are told in the way the "lead" storyteller that starts them. Take that into consideration as Krogg starts this one off.
Plus, I think this one moved the Marvel focus a little back to the kids, and you could tell. My 11 year old enjoyed it a lot! As did my wife and I.
I think people miss the point of the movie. Thor is still my favorite franchise. And will stay, even more so after this one.
