I've seen some pretty good movies over there, though some don't last on the site for long, perhaps these are still there.
Spoorloos aka The Vanishing, 1988 -- A couple are on vacation and the woman gets abducted. The boyfriend spends years trying to find her, even appearing on TV, until he is eventually contacted by the abductor. I found this to be a great mystery/thriller.
Carnival of Souls, 1962 -- An attractive aloof woman who plays the organ in churches sees an apparition of a strange man over and over. This one has a twilight zone vibe. I stumbled on this one day and liked it enough that I watched it again recently.
The Phantom Carriage, 1921 -- A man is cursed because he has to take over the role of Death for a year when he dies on new year's eve. The shining type scene came as a nice surprise, I wonder how scary that was at the time. There are some other great old silents such as Nosferatu and Phantom of the Opera as well.
"November" (2017) -- An Estonian fairy tale horror that made little sense to me but was visually wonderful, then I read some reviews and watched it a few days later and it sort of made some sense. Strange but delightful in my opinion.
Citizen X (1995) -- Based on a book called The Killer Department, this is about the detective who helped catch the worst serial killer in Soviet Russian history. I've seen this one a few times, it has a silence of the lambs vibe and maybe it's almost as scary. Has some great actors too.
