Boring. I went in knowing very little about it, and the title turned out to be pretty misleading. I figured it was going to something dealing with geneology or some kind of tainted bloodline, but it just turned out to yet another satanic cult/demonic possession movie. Nothing original at all. And it had a lot of the things that annoy the crap out of me in modern movies - mainly the annoying soundtrack done entirely on cheap synthesizers and zero character development. Casting was bad too, especially in the case of the son who looked nothing like either parent.
