I love this guy, but I don't even remember him in the movie. I'm sure he shows up somewhere, but he doesn't really do anything.
I would still recommend it for the awesome monsters, but I wish it didn't have so much damn shaky cam. I really hate that. A couple people have also pointed out that the Russians didn't have film cameras with built-in microphones back then. They probably should've just ditched the whole found-footage thing and shot it like a normal movie with some occasional POV shots. At its best though, the movie feels like a ride through a kickass haunted house with a wicked set of nasty bio-mechanical creations. If only they gave us some real characters to care about or some more time with the mad scientist (he actually isn't in it very much). Regardless, I'm sure I'll watch it again just for the crazy creatures. There's plenty of gore too. I just wish they did more with the story and the characters.
