Yes, this movie is weird, and it's entirely intentional.
Yorgos Lanthimos is an interesting Greek director who's been making English language films for a few years. The Lobster is so dry and oddball that I ended up kind of loving it. The Favourite I ended up loving because it was able to most effectively balance its weirdness with its characters (perhaps because he didn't actually write this script as opposed to everything else he's directed).
The Killing of A Sacred Deer is the movie he made in between the two listed above, and I think it might be the weakest of the three. Good instead of very good, that is.
So, let me talk about the weirdness. Everything about this movie feels stilted and mannered. It's off putting, especially at the beginning when you're trying to figure out what on earth the movie actually is. As the story progresses, though, it's easy to see the nefarious undercurrents running through every scene. We spend the first half of the movie trying to figure out where this unease originates from, and the fact that everyone is delivering unnatural dialogue unnaturally heightens the feeling.
I've seen so many complaints of unnatural dialogue over the years. The one example strongest in my mind is around the movie Juno. The complaints of the mannered way in which characters spoke seemed to be a mask for complaints about the rest of the movie that people couldn't figure out how to express, so they picked on the dialogue. I'm not saying that criticism of such writing is invalid or always misdirected, but that did seem to be the trend I noticed and continue to notice in such criticisms. Just because dialogue isn't reflective of how people actually speak (I like to think of Mamet), that doesn't mean that the dialogue is a failure. Oftentimes, it's that way for a reason.
Anyway, back to the movie. The sense of unease that permeates the film is great, and I kind of loved the film for about the first three-quarters. However, once the plot began to unravel and resolve, I felt like the movie lost some of its edge. When the main character is presented with his great moral choice (and his blackly comedic method for resolving it), I felt more removed from the choice than I should have. The build up is what works best in this movie, while the resolution just simply doesn't gel as well.
Still, the movie's an odd but entertaining little thriller.
