Saw it last night and I can confirm that it doesn't suck.
It was freaking awesome!
Even Colleen liked it. She told me she has liked other super hero movies and this time I actually believe her!
I won't give any spoilers away, yet. Rocket Raccoon stole the show, Drax was epic, Gamora was great and Star Prince, er I mean Star Lord was fantastic. Not to forget Groot, Vin Deisel turned in the acting performance of his career. He was born to play the part and I can't wait for the Rocket/Groot solo movie!
Seriously, he showed a greater range of emotions than any other of the characters he has portrayed.
Thanos, Ronan, and Nebula were very effective villains. Ronan is more of a renegade than in the comics. There are a couple of cool scenes regarding the Celestials that blew my mind. The action was intense and well choreographed and it was generally funny! Not stupid funny but enough to keep the theater chuckling throughout.
I'm a little conflicted about what they did with Yondu. The guy playing him was Merle on Walking Dead and he does a great job playing Yondu but the character bears little resemblance to the comics one. Not really a complaint but it was somewhat jarring.
Oh, I loved the Collector as well. The Nova Corps was serious, there was a lot to like about this movie.
P.S. Stay for the after credit scene, I did not see that coming!
