Surprisingly good. If I were Ebert or even Roeper, I'd say, "Witty, entertaining, fun comic book story."
I went into this movie telling D that if I see this one then he has to see Maid Of Honor with me. But I ended up really liking it. And Gwyneth looks amazing with her comic-book-red hair. Annie or Mandy, I think you should do this color next time you dye your hair.
