What's with the colour palette changes?
I liked this movie a lot. The acting and the script were great. I found the fact that, after 16 years of being life partners, he couldn't even attend the funeral because he wasn't considered "family" absolutely heartwrenching (and, unfortunately, it wasn't just the 60's, this still happens: https://www.youtube.com/watch?v=hLeoW17aJ1A). And I thought that's what the title was about: in society's eyes, he was just a single man who lived alone. There was no official record or recognition of his partner's existence and he was not able to mourn his loss in public. I think this fact adds a lot more pain to the loss itself, which is why he was so desperate.
Despite its good elements, however, I found that the cinematography was a bit awkward. Clearly they had made the decision to play with two different colour palettes, the grey-scale one for his present despair and loss of "real living" and the warm-coloured one for his flashbacks and for everytime there was a moment of "real living" in the present. I thought the transitions between the two were a bit abrupt at times. If each of the two palettes had been confined to the present or to the past, it would have been less confusing, though not as original. But with their choice to mix the colours in the present, they would have needed a lot more effort and masterful handling to avoid the transitions being slightly off-putting.
Also, the music was brilliant, I really liked it. I thought, however, that in some cases it dominated the scene and it stole our attention from it, which shouldn't have been the case.
In all, I think the material was great, the actors were great, but there was something off in the execution of the audiovisual aspect.
