A film like mother! was always going to be difficult to understand, so it's no surprise that this is something that Honest Trailers picks up - and the fact that a lot of is, well, kind of boring.
There's also a pointed reference in there about the sink - who doesn't love symbolism? - and the fact that Javier Bardem's face up close is quite disturbing, more disturbing than any other part of the film.
Take a look and see for yourself.
