5) SHAUN OF THE DEAD (Shaun & Liz)

But who says the apocalypse has to be depressing?  Aside from losing his stepfather and mother to a zombie outbreak (which, admittedly, is pretty heartbreaking), doomsday turns out pretty well for British slacker Shaun (Simon Pegg).  After his long-suffering girlfriend Liz (Kate Ashfield) dumps him for screwing up one too many times, Pegg's lovable loser is reborn as a hero, eventually winning back his fair maiden when they're forced to face down an undead uprising with their mates.  The romantic moral of the story is to never take relationships for granted (and, whenever possible, keep your most obnoxious friends away from your love nest by chaining them in a shed out back).

6) THE STAND (Frannie Goldsmith & Stu Redman)

If you think it's hard finding a date now, just wait until a super-virus wipes out most of humanity and the only guy for miles around is the creepy kid with acne who lives down the street. That's the nightmarish romantic scenario facing Ogunquit, Maine resident Frannie Goldsmith (Molly Ringwald) until she meets (and falls for) Texan mensch Stu Redman (Gary Sinise) en route to a gathering of "good" survivors in Nebraska. No such luck for the aforementioned creepy kid, who winds up going to the dark side — and, really, who can blame him when he's literally one of the last men on Earth and still getting shot down by the ladies?

7) THE TERMINATOR (Sarah Connor & Kyle Reese)

Sure, it sounds romantic when a soldier from 2029, Kyle Reese (Michael Biehn), rescues an L.A. waitress from Arnold Schwarzenneger's unstoppable killing machine, then admits, "I came across time for you, Sarah. I love you. I always have." But think about it:  if you were stuck in an apocalyptic future hellscape full of killer robots, wouldn't you volunteer for a mission where you got to have sex with soft, supple 1980s Linda Hamilton (before she got buff enough to pass for a Terminator herself)?

8) NIGHT OF THE COMET (Sam & "DMK")

The near extinction of the human race results in an equally diminished dating pool for Valley girls Regina (Catherine Mary Stewart) and Samantha (Kelli Maroney) in this B-movie classic.  When the Earth passes through the tail of an especially nasty comet, most of the population dissolves into red dust (while half the survivors devolve into cannibalistic mutants). Yet while "Reggie" at least finds a handsome trucker to keep her company, kid sister "Sam" is stuck with an empty dance card (and a bad case of sibling rivalry), which kinda takes all the fun out of battling homicidal mall employees and deranged government scientists. Fortunately, though, the story takes place in Southern California, where even a galactic cataclysm can't wipe out all the cute guys in slick convertibles ready to whisk a gal off into the (eerie red) sunset.
