This is a difficult movie to review or rate. It opens with Catherine taking refuge in abandoned warehouse or military base or whatever it's supposed to be. She's fleeing from some sort of cataclysm that involves lots of explosions. She find some sort of metal cylinder that looks like it fell through when part of the ceiling collapsed and a couple of corpses. From this cylinder emerges the titular last vampyre looking very much the worse for wear.
This is a very spartan sort of movie. It takes place entirely in one, mostly bare room. There are only two characters: Catherine and The Last. That's what the character is called in the credits. Not a lot happens in the movie. Most of it is these two characters conversing about whatever cataclysm is happening outside and why it's happening. Much of that is the vampire recounting the hidden history of the Earth or, at least, his version of it. He is clearly downplaying the predatory nature of his own kind so it's unclear how reliable of a narrator he actually is. A lot of what he says is apparently supposed to sound deep and profound but is really just a lot of vague new age-y rambling. The vampire himself looks quite different from the usual movie vampire. Apparently, the military spent decades trying to kill him so he looks in terrible shape and can barely move around. I am guessing this was mainly to explain why he doesn't just kill her.
This movie was an interesting experiment but it doesn't really work for the most part. Nothing happens for most of the movie. There are only a few mild scares. There's just these two characters talking. If you aren't invested in the ongoing conversation, there's just nothing here.
