I know this movie has been around for a bit, but finally watched Caveat. I liked it a lot! But it is a slow burn, psychological movie, much in the style of Ozgood Perkins--so not a lot of gore or action, but seeped in atmosphere. Also has some unusual twists, and a relatively open-ended ending.
Same director also did the more recent Oddity, which I liked as well (and again, similar vibes), but thought Caveat was a bit better.
