Some people hate this movie for its B-Grade qualities. Ok it's no Citizen Kane but, for me, it's an excellent 'feel-good' horror movie (ie more fun than scary).
I love Richard E. Grant's work and his performance in this is, strangely, amongst his best ~ quirky, whimsical and charming. Julian Sands, doing a campy turn as the relentlessly evil warlock, seems to be having a ball as well. The movie screams '1980s' in places (Lori Singer's clothes, for instance...) but this is nicely offset by Jerry Goldsmith's unusual and timeless score.
If you're a fan of the movie and only have the 4:3 DVD then this Widescreen Blu Ray is a must. Apart from now having the correct aspect ratio, the picture quality itself is much improved too.
