It seems Taika Waititi did the impossible - he made a great and fun-looking Thor film! I know it's just the teaser trailer, and it only seems to reveal parts of the first act, but this already looks like a lot of fun!
It's both a continuation from the previous two films, and kind of a soft reboot for these films. That plus Waititi's unique style and creative tone, and some of that Guardians of the Galaxy humor might have influenced this film. Plus it's part-Planet Hulk and even has some of The Unworthy Thor (the current comics) in there!! What's more to ask!?!
I cannot wait! Thor: Ragnarok will be out by the end of the year, in November.
