Good 3D? Check.
Chris as Thor? OMG check. (loved the fan service scene)
Some mindless humour along the way? Check.

It's a comic book, folks. A great big, dressed up, very glossy comic book — and if you get that wrong, then there's something terribly wrong with you.
Now, a couple of minor cavils: the appearance of Doctor Strange at the beginning and Thor not recognizing him? Sorry, had trouble believing that — and the whole scene, while fun, seems more than a bit gratuitous. ("Hey, we can put in another Marvel character here!"). The Hulk's appearance seemed likewise contrived, with no real reason save to move the plot along a bit. Yes, he plays a big part later, but how we got him there in the first place wasn't really explained any more than "Hulk crash here!" Equally WTF was how a certain other Asgaardian shows up. It was like this planet was Grand Central Station for the universe.
That aside, it's a fun, mindless movie with a lot of great eye candy. Cant go wrong with that.
