Peter AKA Starlord is a scamp, rarely on the right side of the law. But when he realizes that a truly evil dude is coming to attack a planet, he needs to do something--so he writes a letter to an officer (Rhomann Dey) who's arrested him a few times.
Here's a favorite piece- bleeped just a bit so it doesn't set off your net nannies.
Rhomann Dey: He said that he may be an... "a-hole". But he's not, and I quote, "100% a d!ck".
Nova Prime Rael: Do you believe him?
Rhomann Dey: Well, I don't know if I believe anyone is 100% a d!ck...
Nova Prime Rael: Do you believe he's here to help?
Rhomann Dey: ...Yeah, I do.(This transcript taken from IMDB.)
I am all over the idea that there is some good in everyone, and that no one is beyond redemption. This movie is a ton of fun, but it's also about very imperfect beings coming together to make things right, and growing into better beings in the process.
