In all honesty the soundtrack and the inclusion of objects from the '80's is more closer to hitting the nostalgia button than anything. After all nostalgia is defined as "a sentimental longing or wistful affection for the past, typically for a period or place with happy personal associations." Even if Guardians is vaguely similar to Star Wars/Trek, that's more of a coincidence than anything. If you want to see pandering to nostalgia go look at the Expendables, those films are a walking talking pander fest to '80's action flicks to absolute ridiculous extremes. Note: Just because I said see the Expendables that does not exactly mean I am recommending it.
