"Blood Legacy" is one of the most boring and tedious movies I have seen in a long time. It's one of the rare movies that had me almost dropping off to sleep while watching it. Is there anything positive to say about it? Well, despite a low budget, it doesn't look particularly cheap, and director Carl Monson does occasionally makes a striking visual. But for the vast majority of the time, the movie feels extremely flat. There's no feeling of tension or horror at any time, even when the body count starts to pile up. It doesn't help that the movie unfolds at a really slow pace; there's only one murder in the first half of the movie, for one thing. By the way, if you are a fan of John Carradine, you should know that all of his scenes combined add up to less than five minutes of the total running time.
