The cast is decent, but really, does not match up to some other Hammer films. Well, if you are a horror fan, you should at least rent this one, as it is a true classic. Hammer devotees will probably already have it, but if you don't, this is a great treatment for the movie, so don't hesitate. Ok, now my rant is over, so let's continue. The colors look solid, but not many bright colors are used, so don't expect them to leap off the screen.
Black levels are also top notch, with perfect detail, even in the darkest shadows.
Audio 2.0 mono is used, and used to perfection. As expected, some parts are a little worse than others, but overall a solid track. Music sounds good, but in a few places, it sounds very muddled. I was very happy with the dialogue, which is fantastic, with a nice volume and clarity level. Very cool to have these, and if you watch them before the movie, they set a nice mood for viewing.
