I watched Thor Ragnarok this past Friday and it was simply delightful.
Very gentle spoiler about tone and setting.
It really reminded me of Hercules in space. In the 70s or 80s Herc would like hang out in outer space (He was provably being punished by Zeus). It was a fun comic book time. Thor Ragnarok is in that mold. It is lighthearted fun: a romp. I thoroughly enjoyed it.
