I thought Chris H was surprisingly charming -- in the wrong hands Thor would've been extremely wooden given the dialogue and overall cheesiness, but I really really liked him.

Loki was also great, though I felt like the writing of his arc was kind of weak and hole-y. But I did appreciate that he had a lot of shading and that there was feeling there for his brother and family. I came out of it more angry with Odin than Loki which is going to be a problem in later movies when he'll surely be fully villainized.

Love all your bullet points too. :D
