It’s quite common for actors to simply not fit their roles. Yuri Nagibin wrote a story about a very tired man who cannot betray his past and does not want to live in his present with his forever cheating wife. Once in Leningrad, he meets an actress who personifies a possible future for him, she argues with interest with him about architecture, shows his creative friends. She was a dream come true for him, he is a whole man for her, who is just very bad. It can't be decisive and rude, it's not about that, it's about support and acceptance. And Tenyakova here is not at all appropriate, Lavrov is also not very good at playing confused people, he is more about decisive revolutionaries (Pilat will be much later) and those who understand everything. It's a texture, a type. As a result, what is happening in this TV show does not want to believe, the depth of images disappears.
But filmed after 8 years on the same story at the Sverdlovsk film studio "Late meeting" turned out to be much more. Luppian is quite airy, Batalov is really uncomfortable. I strongly recommend you look at it.
