Here's the thing - I actually REALLY liked the movie! I thought all the necessary acts were there, they got Thor's powers and hammer use dead on, the acting was excellent, and the script was actually quite witty and amusing. Were there certain acts that could have used more fleshing out? Sure! Thor's development of humility on Earth certainly receives short shrift, and he definitely goes from being a favorite son to exiled prodigal in the blink of an eye. But overall, I thought it was a really good adaptation of what has proved for Marvel to be an extremely tricky title and character.
The 3D version, however, is utterly POINTLESS and, in fact, detracts from the movie by making certain scenes too dark to watch without straining your eyes. It also suffers from the ridiculous Disney fake 3D nonsense of looking like a ViewMaster toy from the 1950's - layered flat images do not three dimensions make. Save yourself the $5-6 bucks and go see the 2D version.
