I saw this 2 parter on The Horror Channel. I totally agree with the other two reviewers here, part one is lame, looks like an episode from a naff '80s TV prog, is acted badly and George A Romero's talents have been wasted.
Black Cat, the second, however, with a fine actor performing well - Harvey Keitel - manages to carve itself some great scenes, a few of which are truly blood-curdling. Yes, it does need some of its fat cut off, but that's applicable to 90% of horror flicks.
If you are a cat lover with a sensitive nature, this is best avoided. Even though immediately after the last frame has faded we get an American Animal Humane Society certificate that states clearly 'no animal was...' etc, its very prominence means it was heavily on the mind of someone involved that many of moggy's scenes could be upsetting.
As for the actual story, well, it's all a bit over the place but involves photographer Keitel, who hates cats and his common-law wife has a black one. He disposes of it, shall we say and when she gets another, he takes photos of himself "disposing" of that one too, for a book that he gets published. Obviously, his partner isn't too happy about this state of affairs, she moans a lot and then she disappears....
There's a nod or two to 'Psycho' in the way she 'disappears' but I'm not going to say any more than that, apart from that it's worth seeing. It's probably worthy of 4 stars, whereas the first, one.
