Which 80's zombie flick is a better embodiment of all things 80's? Return of the Living Dead or Demons? It's ironic that both movies came out the same year. They both have a striking amount of similarities and for once the Eyetalians didn't steal when it came to making Demons:
Both flicks have a somewhat different take on zombie lore.
Both flicks have punks. Although, Return has the punks as our lead characters.
Both flicks have amazing soundtracks. Funnily enough, the Eyetalian flick has the more well known bands on it's soundtrack.
Return has Tonight (we'll make love till we die) during Linnea Quigley's greatest moment.
Demons has White Wedding play while punks snort cocaine and use razor blades to scoop coke off of sad punk titties.
Of course, you could argue that Return has the more "authentic" 80's/punk soundtrack and doesn't "sell out" like the Eyetalians.
Both flicks have a nihilistic ending.
Both flicks have a meta commentary going on referencing other movies and our main characters in both flicks think that the solution to their problems lie in following the lore of the movie within a movie. Return of the Living Dead references Night ("I thought you said if we hit the brains they'd die?" "WELL IT WORKED IN THE MOVIE!") and in Demons our characters think the movie is to blame ("Please stop it! It's the movie!").
Both flicks have one iconic zombie. Return has the Tar Man while Demons has the poster thing:
It was also used on the poster for the U.S. theatrical and original home video release.
That's all I got (for now). Although Demons does have the better gore it doesn't have the comedy of Return. I think both films are about on par with each other but I think at the end of the day I'd have to vote for Return just because of Linnea Quigley titties while Linnea was in her prime.
