Not outstanding, but definitely not as bad as a zombie rom-com might sound at first. The cast is mostly likable -- Analeigh Tipton, in particular, steals the show as Nora, Teresa Palmer's character's BFF -- and it's got some good moments of humor.
Unfortunately, it is really predictable, especially if you've watched a lot of romantic comedies or seen any of the trailers (which prominently feature shots from the very end of the movie... thanks, marketing guys!). An even bigger issue for me, though, as a horror fan, is its kind of goofy lack of internal logic and the wonky rules for zombies vs. "Bonies."
Kinda dumb, but occasionally fun.
