Working in one of those horror-movie labs where the lights are mostly kept turned off, a small research team discovers a serum that will re-animate the dead. It works on a dog (with some admittedly worrisome results), so when one of the team is killed in a lab accident, an on-site re-boot seems logical. David Gelb's film could have worked as a decent thriller, a compact survival tale of five people — one of them undead, angry and super-humanly strong — trapped in a confined space. But instead, Lazarus is 83 minutes of jumbled set-up that goes nowhere: playing God, religion vs. science, afterlife (yes or no?), PTSD, energy transformation, corporate espionage, the pros and cons of academic research grants, a crazed dog on the loose, a wandering security guard ... But then the film just stops. Seriously — nothing is resolved, except the likelihood of a sequel. But don't be fooled by a potential re-birth: This story is DOA and beyond resurrection.
