Not your run of the mill horror movie, jump scares or blood and gore, but quite some psychodrama - and a surprising end. Pay attention to the beginning.

Oh cute, another movie about manipulative psychologists who pretend to be "helping" patients while they're really just indulging their own sick narcissistic delusions.

Verdict: Psychologists who think they're oh-so-clever should stick to simply tormenting their captive audience of patients, not write ridiculous movies to torment the rest of us. Adding an extra star for the Floor Pie bit; that was legitimately funny.

This is an innovative movie, and I don't understand those who criticise it. We need to applaud and support production teams who are prepared to break standard rules and codicils.

I enjoyed it - and I learned stuff.

Bravo!
