My honest review of GotG posted on metacritic... I love everything Marvel Studios and hated Man of Steel:
You know there's something terribly wrong when the most memorable part of the movie is the sequence after the climactic finale... yes, I'm talking about a baby dancing Groot. There was nothing about this movie that really drew me in, and it's because the character stories were rushed so fast that you didn't get a chance to feel anything for them. We get to see each character for a few minutes before their paths collide. So when the characters only know each other for a few days, we're expected to believe they've bonded to the point where they'll die for each other? This movie should have been an animated film for kids in my opinion. The dumbed down dialogue sure fit. I really wish they focused the story on Peter Quill, instead he felt like a side character. That's probably because we have five heroes, four villains, and tons of side characters: Yondu and his crew, the Collector and his slave, Nova Prime and the entire Nova Corps. So many pointless characters could have been cut from this film, and the necessary time could have been given to develop Quill's story. This would have improved the movie dramatically. Don't get me wrong... all the characters in this movie do look really interesting, however, you can't squeeze all their stories in a 2 hour film, otherwise it's a mess. The directing was great, the overall story was good, the action and special effects were superb, but the characters are so shallow... the core flaw with this movie is the numerous characters that shouldn't be in a film that's introducing the casual viewer to a completely new universe. Keep it simple. This is not the Avengers, where each super hero already had their own individual films that established their character's background.
