Trailer: 'Guardians of the Galaxy'

Well, this trailer for Guardians of the Galaxy is, in my opinion, odd. I really like some of what I see here, I feel I don't know the 'tone' this movie is going to have. I've been hearing things like "It's raiders of the lost ark meets the 5th element" and if thats the case it will be the best film of all time.
But with this trailer I'm not sold, I want to be sold but I'm not.
