Mileage may vary. The action is awesome, but only some of the humor worked for me. The visuals are stunning, but much of the plot only pays off mildly well. It's not a bad film by any means, but it's only 'fine' when it could have been 'great'. It's candy, not meat and potatoes. It's fun, flashy and fleeting.
Honestly the fact that the trailers ruined so much of the movie was very disappointing to me. There's like 20 minutes of build-up to "who is Thor going to fight?", but that was in the first 20 seconds of the trailer. And for as amazing as many of the costumes were, Valkyrie's costume was one of the worst I've seen in any super hero movie. Who thought "You know what's a badass color? Taupe."
