An all-in sentimental/comedy: Peter the very abandoned orphan meets his father at last, with highly ambivalent feelings on both sides; meanwhile, Peter's crush develops into a proper love story; his girlfriend also recovers a positive relationship with her sister, who stops hating her; his goofy sidekick meets the right girl to fall in love; his badass companion discovers the power of being nice; a beloved friend dies with lots of mourning; silly misunderstandings with dangerous people keep our heroes moving.
Of course this is all very, very wrong. Peter is Star-Lord, supposedly a hero, but due to disagreements with his father
Spoiler
Apart from characters, tone is also painful: serious moments and issues are "lightened" (actually wasted and ruined) with silly lines and distractions, the expected saving-the-galaxy business manages to be both a disturbance and a boring job, a disturbing number of mooks is slaughtered.
