I was afraid of that.
Speaking of cruelty, though, I've been conducting a little Yorgos Lanthimos film fest the past week, watching The Lobster, The Killing of a Sacred Deer, and Dogtooth. Holy crap, are these tough watches. The easiest was The Lobster, which I'd expect has been previously covered in the thread, and at least has comedic elements, albeit black, black, black. Actually I found comedy in The Killing of a Sacred Deer, too, though I'm not sure if I was supposed to. Both that and Dogtooth are really rough to watch, though.
His movies remind me in a way of Lars von Trier's. So bleak, so cruel, and often with that same purposefully wooden acting style that von Trier seemed to cultivate. von Trier's films seem to have had more an emotional impact on me, maybe by being less absurdist than Lanthimos's.
Lanthimos also directed but did not write The Favourite, which I haven't seen yet but appears much more mainstream, probably since he was not the writer. I do recommend The Lobster and The Killing of a Sacred Deer, but only if you have a mental state that can withstand "extremely dark" right now. I wish I'd waited for a less overall depressing time to watch. I'm not sure if I recommend Dogtooth, but if you like the first two, it's worth a shot. Also, Lanthimos clearly has an obsession with hair that rivals Quarantino's foot fetish.
