I'm always on the lookout for good horror. Oddity is almost "perfect". This could easily be a 7 or 8. Instead it's a 6, or maybe a 5. The final act just didn't work for me. The big reveal is fine, but what happens after the big reveal makes little sense to me.
There's also a bit before the big reveal - let's call it the small reveal - where the logic just falls flat too, but I was willing to ignore it at the time. Unfortunately, it was a sign of things to come.
SPOILERS AHEAD!
The more I think about it, the less sense it makes. Darcy learned the full conversation from Olin posthumously. How the heck did she not learn anything from Dani's personal effects? Furthermore, they really went ham on Ted's stubbornness for the climax. Ted now has at least six unexplainable events and he still goes playing with the thing?
