This is a very, very good movie. Lots of fun, excellent animation, and really good writing. Shockingly, the hero's choices don't just all resolve themselves -- even in victory, there are lasting, believable consequences for him. About the only quibble is that the Vikings have Scottish accents. Part of me is choosing to believe they converted to Vikingism for the chicks.
Also, if you've never dreamt about riding a dragon I don't even wanna know you.
