I've never been a fan of any incarcation of the GOTG comic or otherwise, the movie was just ok and not fantastic as critics are raving about. Marvel Studios simply wanted to play it safe with what the moviegoing audience is comfortable with and simply made a thinly veiled carbon copy of the Star Wars formula and tropes.
And not that it's a bad thing since imitation is a sincerist form of flattery I mean god knows how many Star Wars rip-offs there have been but there was no originality, now that Disney owns Marvel they're trying to pacify their movies and make if family friendly for merchansising, theme park purposes.
