A Cure for Wellness (2016)

I must have read positive reviews about A Cure for Wellness if I decided to add it on my watchlist. I can't remember though as I kept putting it off forever because of its length, two and a half hours. I mean, who's got time and willpower to watch such a long horror? I'm talking to non-horror lovers like myself. Anyway, I finally check it out and damn, it was good. 

The film follows Mr. Lockhart (Dane DeHaan), a young and ambitious financial executive from New York who is sent to a mysterious wellness center in the Swiss Alps to retrieve his company's CEO, Roland Pembroke (Harry Groener), whose signature is necessary to complete a merger. It is supposed to be a very easy task but soon Lockhart begins to question the true nature of the center and finds himself trapped at the wellness center as well.
