Watched this last night.
It's from the same director as 'The VVitch' and as expected (and as I am sure you can tell by the trailer) it's a bit of a brain twister of a film.
It's probably best described as a psychological thriller, a claustrophobic descent into madness, as the 2 main (and only) characters played by Willem Dafoe and Robert Pattinson are stranded on a storm ravaged island (where they work as lighthouse keepers) after their relief boat fails to arrive.
Brilliant performances from both actors here. Anyone concerned with Pattinson landing the Batman role in the upcoming film should take a look at this. He's certainly moved on since his sparkly vampire days ( lol )
It's filmed in an old 'square' aspect ratio and in black and white to give it that 'old time' feel and adds to the claustrophobia of the whole thing.
I really enjoyed it, but be warned, much like The VVitch, it is a VERY slow paced movie and an intensely strange one at that, which ends leaving you with way more questions than actual answers. It is quite 'artsy' in that respect and quite a difficult watch if you're not prepared for it. - so avoid if you're not into that kind of thing.
