I diavoli delle tenebre

This is basically a Hammer Films knock-off, in terms of set decoration and production design. The result is a nice-looking movie with a muddled, incoherent story, weak acting, and limp direction. It's not exactly excruciating to sit through, but it's one of those films that makes you feel you could be doing something better with your time.

The plot is a mixture of vampire and devil worship, and although there are one or two good moments, there's not enough substance to make it particularly interesting.

If you're fond of campy/cheesy B-picture horror, you might want to give this one a look, but I wouldn't put it at the top of your list.
