Closer to God is a modern revamp of Frankenstein, and it somewhat straddles the genres of science-fiction and horror, or at least tries to. While there's a large attempt of things that seem scientific, I really feel like that area was so underdeveloped that I just didn't find that at all convincing, even for suspending disbelief for the purposes of a film. It's what comes of a film trying to make some pretty broad claims about science without really exploring or addressing them. The horror film aspect of it has its moments, and while I think it did a very good job of building up tension, it really seemed to fall apart when it came time to cash in on that by being a bit blunt about it, after doing a fairly good job of building up the unease and mystery.
There certainly are some other interesting questions that are at least mentioned about what represents humanity and how cloning factors in, and it acknowledges a lot of issues with the ethics, philosophy, and spirituality of cloning, but it doesn't really explore or discuss those issues much. It opens the door to them, and I do give it some credit for not pushing a particular answer to those questions, but I feel like more could have been fleshed out with them.
An overall slow pacing, I think it could've been made up for with stronger points, both conceptually and thematically, instead it fizzles out a bit at the end.
