Personally, I thought the standout character was [BLACKOUT]Groot. Despite just three words of dialogue and a lack of a backstory, he still manages to steal a majority of the scenes he's in. Whether it's those bits of comedy that had me laughing my ash off, or those awesome action scenes of a living tree kicking ash, Groot was a joy to watch. I give the CGI wizards and Vin Diesel all the credit in the world for bringing to life such an amazing character.[/BLACKOUT]
[BLACKOUT]Batista as Drax would be a close second. Leave it to James Gunn to find the comedy in such a straightforward one note character (though not exactly one note as you'll see).[/BLACKOUT]
