How bad is it? It's not good. Not good at all.
Should you see it? There's a 0.00001% chance this will get a cult following; watch it if it does.
First of all, there's some question as to whether the title is The Becoming 2015, or not. It's slow, over-acted, with overly dramatic music, it has time warps, zombie vampire demons, an angel wielding a light saber (!), meteors, side plots with hookers that go nowhere and a trick ending you'll see coming as early as the opening credits. It's marginally funny, if you're in the right mood.
