Is 'Guardians Of The Galaxy' The Best Marvel Movie Ever?

It's Groot. It's very, very Groot.

In a matter of weeks, "Guardians of the Galaxy" will be available for all the world to see. But some lucky people have already visited Marvel's cosmos — and if you're not jealous yet, you're about to be.

"Guardians of the Galaxy" opens on August 1.
