You've probably seen my go-tos for casual viewers: Sunshine, and Cube

I'd recommend some throwback MST3K. 

 I've not seen Sunshine but have seen Cube. I like MST3K too lol. Thanks for the reply! 

 Event Horizon? 

 I've seen it but good movie! Thanks for replying 

 Blue Sunshine
Satan's Little Helper (more a comedy but thematically horror)
My Sweet Satan
Deathline (1972)
Crawlspace
Bad Ronald
Warlock
Pin
session 9
wendigo

Hopefully you haven't seen at least one lol 

 Pontypool? 

 Never seen that one either. Looks like i have a full-blown movie night coming up lol 

 Wow! Nice list. I have seen Warlock and Wendigo, but all the rest are new to me. Thanks! I will be sure to look them up 😀

 House (1977), Nobuhiko Obayashi. 

 This is different than the House I am thinking about with William Katt, right? 

 This «House» I suggested is a japanese film. I dont know if there're any connection between them. 🤔
But, anyways, thanks for this collateral suggestion. 😅 

 Have you seen Hereditary? Late Night with the Devil? 

 I've seen Hereditary but not Late Night with the Devil. I'll look it up. Thank you! 

 Hereditary by Ari Aster
Midsommar by Ari Aster
Suspiria by Luca Guadagnino
The Witch by Robert Eggers
Longlegs by Osgood Perkins 

 Seen all of them except Suspiria and Longlegs. Wil check them out, Thank you! 

 You’re welcome! 
Glad I was able to find a few you didn’t see 

 Longlegs is peak Nic Cage. It is an otherwise average crime procedural turned gonzo by his presence.  

 The Descent is always one that sticks with me. So claustrophobic. You couldn't pay me to go into caves like that. 

 Not necessarily horror but give Free Solo a try, a documentary about a guy who does rock climbing without safety gear. I still get sweaty palms just thinking about it 

 silence of the lambs is akways great
