A few non-modern (however you’re defining that) horror movies I watched recently that kick ass, especially if you like suspense and/or black humor:
Diabolique and
Pretty Poison and
The Stepfather (1987).
For those who have Filmstruck, I highly recommend the hard to get anywhere
Cure, a horror/mystery classic.
I saw
Henry: Portrait of a Serial Killer recently too, but I can’t recommend that (even though it has genuinely funny moments and good acting all around, esp from the two male leads). It’s just too hardcore.
On Prime I caught a strange one … It has two titles and I can’t remember which one Amazon uses, either
Night of the Eagle or
Burn, Witch, Burn. It’s a great-looking B&W, compelling even with its silly premise. Briskly paced.
I'd enjoy hearing any thoughts/recommendations.
