Talk about disturbing. I'm slowly entering the fantastical world of canadian horror...whenever I watch a certified weird horror film, I look it up and it's from Canada (a.k.a. "Things").
This is no tacky slasher, mind you, but it's also not pretentious psychoanalytical BS, it just is. It's smart enough to leave space for personal interpretation at the end. I'm always one to complain about the horror genre being a copy of a copy of a copy, but this...well, it's been 29 years since "Pin" came out, but it's worth checking out.
