Thor - Ragnarok. Follows the basic Marvel formula.
If you like Avengers (not Jane Peel...), Iron Man, Ant Man, GotG... then you'll probably like this. It's knowing, laugh out loud funny, fast paced and a good bit of entertainment. But entirely inconsequential.
If you haven't seen these then I'd wait until home release (or simply watch Avengers Assemble which remains the best example of the Marvel universe).
