It wasn't as much fun for me as Thor even though it had better writing and acting, for the most part. It was less pure escapism, less visual, and a bit more thoughtful (I just really love pure escapism). Similar amount of slashyness, though. I'm sure it'll be vidded to pieces.
Casting was very smart, and the cameos were brilliant. I'm hoping for a sequel, but looking forward to Avengers more.
