Atmospheric and with some decent performances but this gets lost in it's own complicated Ten Little Indians story. Nice touch with the creepy looking cat arriving to herald each killing but it's not enough. It's all rather slow and uninvolving (till the end) but it's interesting to see a young Birkin and I'm sure I've never seen Serge to looking so young. Inconsistent to say the least, this seems to drag because there is not enough to hold the attention. Not unlike a lesser Hammer production in this respect which to some extent it does resemble. Musical score all over the place too and this doesn't help. So, very average, great poster though reproduced on the DVD cover!
