Guardians of the Galaxy Trailer

Today we got our second (and better) look at Marvel's upcoming gamble: Guardians of the Galaxy. I say gamble because this film can either succeed and make a tonne of money or flop and leave a black mark on marvel's amazing track record which started during phase 1. The trailer finally gives us scenes with Rocket Raccoon talking which people have been wanting to see for ages because Rocket Raccoon will definitely be the star of the show and the most memorable character if he is done properly and marvel need to sell Rocket Raccoon hard so that kids buy the toys and boost sales. Despite sales figures the trailer does look amazing and shows that movie is taking a more light hearted and fun vibe as opposed to a darker vibe (such as in the Winter Soldier). I hope that this movie doesn't sacrifice a good story just to please children because I've been looking forward to this movie for a while and after Iron Man 3, I just don;t want to see another failure because Marvel stories have so much potential. Please be good Guardians, PLEASE!
