An '80s slasher movie I never heard of? How can that be? Oh, I get it. It's, uh, not very good.
I only found _Curtains_ because I love horror movies set during winter, particularly when there is snow.
While there are several great qualities here, the movie overall just falls flat. Where to begin? I think it's important to understand that, much like other slashers from the era, this is a whodunit; trouble is, all of the girls look alike, so I was never sure who was dead and who wasn't. What the movie gets right is the score, the lighting, the overall atmosphere, and the tension.
_Curtains_ has a very slow build, but that's fine, because it does a magnificent job of becoming claustrophobic and interesting as the bodycount raises.
I thought I was going to like this, but the ending just comes out of nowhere, and there was a plot hole so big, I thought a scene was missing or I blacked out. Really just lazy writing. I mean, most slasher movies rest on the explanation being "crazy though." But this? Come on!
All that will stick with me about _Curtains_ is the killer's mask - truly creepy. That and how well the cold, dark environment was captured on film.
If you love old slasher movies - e.g., _Black Christmas_ (1974), _Friday the 13th_ (1980), _My Bloody Valentine_ (1981) - I'd still recommend this. Just know that it hits different than those. That is to say, it feels as if they wanted to make a psychological horror movie, but wanted to cash in on the slasher boom.
