I read somewhere that this is as much a Lamberto Bava film as it is Mario Bava's. If it's Lamberto; it's one of his best, if it's Mario; it's not one of his best.
Shock mostly delivers in a knockout finale that is truly terrifying. Up until then it mostly drags, with highlights that are few and far between. This is not one of Bava's visual feasts, it's more gritty looking than I expected but Bava is, as always, very capable of creating a moody and eerie atmosphere and he doesn't fail here either. If the film had a better script and a few more surprises up it's sleeve it would be a superb horror movie.
The film is also bolstered by Daria Nicolodi's best ever performance, pity she didn't perform as well for Dario Argento as she did here. The fact she could act so well here was a big SHOCK for me.
