Jokes aside, I thought this was a pretty good arc and a necessary one. Sakuta is so use being the remedy of all the girls' trauma that I wouldn't be surprised that this movie wasn't the most well received. I am also not very emotionally invested in Sakuta as a character, he's also dating my wife, so I am conflicted.
Sakuta's situation isn't given enough attention and I respect that the author took the risk to do an arc dedicated to him only. He had it tough and there's valid reasons for resentment, hell through out the series I thought he was getting screwed by his parents and he's just chilling. Forced to grow up due to both parents failing you is shitty. The dad is mostly to blame to be honest, his actions were extremely selfish and somehow Sakuta was fine with him and places the blame on his sickly mother. When he finally accepts his currently living situation, he's thrown back into the messy family dynamics. Of course he wants to be a family again, but this could be seen as another stressful situation where he too will have to adapt to. They were definitely grasping at straws though to give enough reasons for Mai to be there if at all beyond the couples dynamic at the start. Kaede would had made the most sense as the supportive role, but they needed Mai's face to sell tickets.
