Not a genre I watch much

But I looked over the list and saw a few that I've seen and some the I actually liked.

Netflix
Train to busan (Not zombie guy but probably the best zombie movie I've seen)

Killer klowns from outer space (My favorite "B" movie of all time, one of those movies that's so bad its good)

Apollo 18 (Not a classic but worth a watch)

Prime
Cabin in the woods (Horror movie with a twist, liked it better then most)

Phantasm (70's cult classic)

House (For sure worth a watch)

Invasion of the Body Snatchers (Classic)

On a side note when I was looking through the list I noticed Prime has all the original Outer Limits episodes from the 60s.
