I'd be surprised if you didn't find it at least watchable, seeing as you enjoy Dead Alive, zombies, and of course, necrophilia. It has a good Christmas vibe, a memorable protag, a few splashes of blood, a few bits of gore, and a downbeat ending. The acting is good to passable, and the direction is solid. And again, it has necrophilia, which you love. It's a low budget film, but the director has the panache to make you forget that point. This is his first film; he was clearly influenced by The Evil Dead and Dead Alive in terms of cinematography. On the downside, he employs elements of the grindhouse aesthetic (false grain and cigarette burns).
