I saw the movie this morning and I thought it was absolutely amazing. I loved every moment of it. Anne Hathaway was awesome as Selina. I do agree that it was a little more over the top than the other two, but IMO it wasn't extreme enough to ruin the movie.
I'm actually really glad I read about Talia, because I thought it made it alot more interesting being able to watch Bruce and his allies basically give her everything she was after. Definitely an Excellent
