BlakeCrane’s review published on Letterboxd :
"Session 9" had been in my queue for quite some time and I'm glad I finally caught up with it. Was inspired after being pleasantly surprised by Brad Anderson's "The Call" and was even more impressed with this film.
It sets up the situation beautifully and the location is perfect. It is ominous and rundown, because it's ominous and rundown - it's not an obvious set creation. Tension builds throughout and we aren't insulted with flash cuts or cheap jump scares. A fantastical story is presented in a straightforward manner that was hypnotic in a strange sort of way. But a very entertaining way. A slow burn that delivers.
