I'll follow horacethegrey's lead and mention that there are SPOILERS BELOW.
I liked it, but thought it fell below the Iron Man films. Sif and the Warriors Three didn't impress me at all; they seemed artificial. I "bought" Thor, Odin, Heimdell, etc. as looking natural in their armor, whereas Sif and the Warriors Three looked more like actors in Ren Faire garb. (To quote a SHIELD agent from the film, "We've got a Xena, a Jackie Chan, a Robin Hood....") I don't think they did much in the way of explaining the Odinsleep, other than mentioning that it's happened before, just not with this quick of an onset (in which case they'd expect him to wake up again eventually, so how does Loki get to crown himself king?) Black Heimdell didn't bother me at all, since they took a technological approach to Asgard; a Black Asgardian works fine if this is a race of beings elsewhere in the Galaxy, whereas it would have been a pretty silly move if these Asgardians were actually the Norse deities. (Plus, the guy playing the role did an excellent job - he was one of my favorite characters in the movie.) I wasn't put off by the smaller-than-expected stature of the frost giants, especially since the frost giant king (Laufey, was it?) was sufficiently imposing.
On the plus side, I thought the Destroyer was a cool villain for the movie. And the destruction of Bifrost isn't that big of a barrier to getting Thor back to Midgard in time for the Avengers movie, given that the movie hinted at two different ways to get around it: there are hidden ways to get to Asgard besides Bifrost, and that Mjolnir is a tool of creation as well as a weapon of destruction.
As for the scene after the credits - everybody knows to hang around for the bonus scene after the credits by now, right? - it looks like the Cosmic Cube showed up. I wonder if that's going to be a plot point in the Captain America movie, given that the Red Skull was after the power of the Cosmic Cube. (Maybe that's how they'll get Cap from WWII to present day, instead of having him frozen in a block of ice and worshiped by Eskimos.)
