7/10 for me

The basic premise of evil/multiple characters in one mind has been done before for sure, but I was impressed with the presentation here.

The explanation is goofy-as-hell, but I could roll with it and enjoy this movie. I'm one of the viewers who was slow to catch on to Gabriel's true nature until well into the movie. All I knew is that he moved in some freaky way that suggested he might be supernatural. The eventual reveal was a "Whoa" moment for me and I'm usually good at guessing these things before they happen.

i'll prolly watch this again next Halloween too.

Sidebar: At times the main actress looks a lot like a younger Uma Thurman to me. Gabriel's look and movement seems heavily inspired by the creature in Lights Out if you are looking for a similar movie.
