Bloodbath at the House of Death

 Bloodbath at the House of Death is a fairly witless 1984 British comedy that reads like an attempt to do an Abrahams\Zucker style parody by way of Hammer Horror, but comes out feeling like a particularly unfunny Carry On movie, or a Benny Hill skit.

 There's a couple of decent jokes here and there, but for the most part it trades on mild subversions of expectations without a decent punchline. Or even worse, just thinking some mundane thing is intrinsically funny and letting it play out: Hey, this guy is blind! Look, he crashes into things all the time! Or look at these two men, they're gay! Here they are, liking other men! It's... pretty fucking terrible.

This, I'm sorry to say, is representative of the humour within.

 It starts out all right - likeable, if not actually very funny, and with a high body count as well. In a short pre-titles prologue a terrible massacre is carried out by a bunch of monks on a secluded manor house. A few years later a group of scientists go in to investigate, and spooky hijinks ensue. You get your requisite references to then-recent(ish) Hollywood hits (ET! Carrie! The Entity!) but unfortunately the movie never has the grace to more closely emulate its obvious influences (the great Top Secret! was released on the same year.)

 Besides the humor, the film is not exactly Z-grade. It boasts a decent budget for what it is - there's a few big scenes with a lot of extras and a decent amount of locations, but it still looks cheap and tacky throughout. The gore and makeup effects are uninspired, but perfectly fit for purpose. The acting ranges from "they did what they could with the material given" (this includes Vincent Price, classing up the joint a little) to painful to watch (Kenny Everett, who I'm happy to say I'd avoided up to now and will continue to do so; Reading up on the movie, it came as no surprise that he was a radio jockey.)
 Director Ray and co-writer Ray Cameron is a British TV guy through and through, most known for the long-running panel show Joker's Wild and a some stuff with Kenny Everett.

 Just... seriously, unless you have some fondness for even the worst of the Carry On films, don't even bother. There's a dearth of real laughs to be had here, and the few decent jokes (like someone getting decapitated with an electric can opener, or... um, a cute bit with a bookcase, I guess?) are few, far between, and better on paper than in execution.
