The ending (no spoilers in post)

I liked the whole film up to the final act. I felt it tried too hard to be clever and it just fell flat.

I wish horror films would go back to just being straightforward and lose these type of twisty try hard endings because more often than not, they don't work.

I don't think i'd even classify this as horror, but more suspense/mystery, which isn't a bad thing. It kept my attention through to the end.

I give it a C-. (The minus goes for the ending, otherwise i'd rate it a solid C.)

If you're into suspense/mystery it's worth a look.
