This isn't going to be an eloquent review, just wanted to remind the Bex of the future that this is an incredible film.
One thing I found disconcerting was that I didn't feel like I had much of a frame of reference, a lot of it was incredibly alien, particularly the aggression in the relationship between the two main characters. It was a deeply sad film, though by the end I definitely came away with hope. Because there is one character in it who has hope, who has dreams, and even though none of them are realised, and even though he suffers for them, they are worth it. So that was a good 'message'.
There was a bit at the end where someone who has lost someone they love visits the parents of that person, and the whole encounter really rang true. It's that thing of clinging to the things left behind by someone, and feeling like if you let go then they'll really be gone... or something...
