This was advertised at my local cinema as a Comedy Drama. Well, there's no comedy in it.
In 1877, Tchaikovsky married Antonia Miliukova. Six weeks later they separated, although they remained legally married until the composer's death. This is the story of that marriage and its aftermath, told from Miliukova's point of view. It's clear from the outset that she's an unreliable narrator of her own life, and we can never be sure how much of what we see is real, and how much is happening in her head. This is made clear in one early scene (probably the best scene in the film) which does at least pack a surprise.
The rest of Miliukova's descent into madness is shown in a way that is intended to shock, rather than surprise. There's a lot of frankly gratuitous nudity depicted in a manner which is (presumably deliberately) as subtle as a brick and as tasteful as a colonoscopy.
The performances of the two leads are good, the cinematography is excellent, the set designs are interesting and the level of surreality is dialled up to the max.
The problem for me was that Miliukova was not in any way portrayed as a sympathetic character, and it's not very easy to warm to Tchaikovsky either. The only really likeable characters are the roguish Bochechkarov, and a gossipy woman whose name I missed, who get all too little screen time.
The sound-track is atmospheric, but features none of Tchaikovsky's music, which was a disappointment.
An interesting film, but not really an entertaining one.
