Strange Thing To Say About A "Horror" Movie ....
But .... what a sweet f%&king movie !!.
It was a creepy twist on mental illness, but ultimately it was about one trouble friend helping another troubled friend. And it didn't end in a nasty, unsatisfying way. The one friend put all of his trust in his ill friend and the joy that Wyatt had at the end (seeing Christian was still himself) made me happy. It was a really satisfying ending for me.
I thought the actors were all really good (including the actress who played Mara. The friendship between Christian and Wyatt was childlike and oddly homoerotic.
Certainly, Mara's initial reaction to Wyatt in the basement was more realistic, but Christian genuinely wanting to help Wyatt, not showing fear of him and playing along with his delusions was touching (and obviously dangerous).
There was enough creepy imagery and disturbing scenes that it didn't bother me at all that the movie wasn't 'horror' horror. And I liked that ultimately the mentally ill Wyatt didn't hurt anyone (his ex girlfriend, Mara, Christian)
