Glad you liked Sauna, one of my favorites, and agreed big time on The Burrowers and Dead Birds--not enough historical/western horror, though Neil Marshall is apparently working on "a Lovecraftian western," so we can hope it's as awesome a film as the combination of those two words implies it should be. Praying to the old ones the tone is closer to The Descent than Dog Soldiers.

The last one I mentioned, Eyes of Fire is super hard to find and really, really weird--almost a Blackwood/Machen/Lovecraft feel to it at times, and I remember being pleasantly surprised despite the budget constraints. It's been a while, though...

Also might have added The Fearless Vampire Killers if I didn't have such a vexed relationship with it--a childhood favorite, and a beautiful, atmospheric, and charmingly silly film with a great soundtrack, but it's not only directed by Roman Polanski but also stars him, which I imagine might be triggering for some people. It also stars Sharon Tate and was made before Polanski's degeneracy into human filth, and seeing the two of them share the screen before everything went to shit adds a very palpable pall to the film--but it's an intrinsic part of my childhood and nigh-unheard of nowadays, so I thought it deserved mention.
