is their like a planet with raccoons as a race, Can someon explain this character to me?

Racoon Green Lantern I can't say.

Rocket Racoon?  He's  a regular racoon who was genetically modified to guard insane mental patients.

the choice in music for the trailer doesn't inspire confidence..

Out of all the superhero movies coming out this year, this one is probably my least hyped mainly because I haven't heard of GotG until just recently.

I enjoyed the trailer because it gave me a quick rundown of the main characters, and it does look kind of fun. Wasn't boring unlike X-Men's Future Past trailer. Marvel does have a good track record as of late, so it should at least be decent.

It has Chris Pratt. It has to be at least decent.
