Simon: Man should live and let live, and without any interfering.
Paolo: Even that poor squid was free once, Simon, eh? I study Coleoptera because I love them.
Simon: Sure, but the squirming little creatures still end up under your microscope. Yeah, he's dead all right but at least I eat my squid. But I don't kill as a hobby like you do.
Paolo: Good lord, Simon. You make me feel like a murderer.
Simon: I'm not saying that, Mr. Fossati, but if you kill for killing's sake, you become a monster.
Paolo: But, man isn't an insect, my dear Simon. ...

It does what it says on the tin
5 July 2017 | by MOscarbradleySee all my reviews

You don't go to a Mario Bava picture expecting an Antonioni picture or a Fellini picture. Bava does exactly what it says on the tin and what it says on the tin here is "A Bay of Blood" so basically you know what you're likely to get and what you're letting yourself in for but Bava is as much an auteur as any Italian maestro and the killing that opens this film proves it. Working almost exclusively within the genre of the horror picture Bava was, above all, a great visual stylist, (as well as directing "A Bay of Blood" he was also the DoP), and unlike most films that might be termed slashers this could almost be called art, albeit of a very kitsch kind.

Budget-wise Bava had to achieve his effects with very little, other than sheer imagination. "A Bay of Blood" may be a fairly basic giallo in terms of plot but it is also creepy and clever and thankfully tongue-in-cheek, (with a laugh-out-loud pay-off), and Bava knew that by including a few 'cult' names in his cast, (Isa Miranda, Laura Betti), he could draw in the cineastes. It may not be in the same class as some of his better known works but it's still worth seeking out.
