I had the pleasure of seeing an advanced screening of Guardians of the Galaxy last week which was, well, everything I dreamed it would be from the very first preview I read of the first issue in 2008. You can read my full review over on Tor.com (with whited-out spoilers, for those of you worried about those kinds of things).
You can also listen to this totally sweet Star-Lord jam by nerd-rapper extraordinaire Adam WarRock (although I personally would have preferred it if he had sampled from "Hooked on Feeling" or one of the other delightfully anachronistic songs from the movie soundtrack like he did for his Firefly mixtape, but that's a minor gripe).
