It is reassuring to know that even after the zombie plague begins in earnest, a strong vein of Jewish humor will thrive. This is the best news to come out of the superbly titled Life After Beth, a comedy that kneads together the relationship movie with the zombie genre. After opening with a brief glimpse of the title character (Aubrey Plaza) jogging into the woods toward a fateful encounter with a poisonous snake, the movie turns to the grief of Beth’s loved ones. Beth has died, and boyfriend Zach (Dane DeHaan, from the most recent Spider-Man movie) can’t seem to let go. When she comes back undead—confused, but otherwise energetic enough—they resume their romance. Because Beth’s parents (John C. Reilly and Molly Shannon) insist on not telling her about her death, Zach has a difficult time explaining why Beth shouldn’t leave the house much or be seen by people.
