Yea I know how you feel. I went with my roommate the first time and she seen most of the movies, and knows probably bunch of the comic stuff through her sister, and has seen Joss Whedon stuff too and liked it. Then I saw it again with my friend who hasn't seen any of the movies or Whedon shows and loved it too.

I completely feel ya about the "it's Joss Whedon and he is awesome" that was my initial reaction to the movie. I knew it would awesome because of Joss and I was correct. I never been so sure about a movie that I've never seen before like with this one!! haha
