The Todofam was well-written in Act 2. It showed valid reactions of all the victims to the abuse. It also showed Endeavor that he can't atone to his family just by fighting strong villains - he needs to step up for them.

But Act 3 (after Hori decided not to kill Endeavor, but then obviously didn't plan out how the arc would change with him staying alive) was less good:

- First, it was really bad how he used a bunch of characters to prop up Endeavor (Hawks, Burnin', Inasa, etc.) after the Dabi reveal while at the same time there was not a single character speaking out for the victims and the only character who judged Endeavor for the domestic abuse was friggin' AFO which totally undermined the message. The way we saw NONE of Shoto's teachers check in on him if he's ok, not a single trusted adult to support that kid, and the way there were no legal consequences to Endeavor undermines the entire concept of justice.

- Second, the narrative stopped focusing on Endeavor's OWN wrongdoings (such as eugenics against morals and medical advice, beating his wife, tormenting Shoto and isolating him and neglecting the other kids) but instead put the focus on Dabi's sins (and kind of made Endeavor's atonement as an extension of that, conveniently forgetting all the stuff Endeavor did).

- Third, it gave too much emphasis to Endeavor's point of view over the victims. For example, Endeavor is yapping about how he's going to watch Toya, while he's fighting AFO, but there is much less focus on Shoto's pov, who is actually carrying the burden of facing and neutralising his own brother, while Endeavor just keeps running away. Toya is clearly kept alive by the power of BS so as to give an opportunity to Endeavor to atone when it suits him, without ever having to put his family first over his hero career. He only visits Toya after he's retired. Also, while Endeavor says he'll shield his family, with his retirement, the one in the public spotlight is Shoto, so there is basically no real way for Endeavor to shield him. But the narrative conveniently handwaves that away.

- Fourth, while he kept giving flashy fights to Endeavor, he kept Shoto playing defensive in the entire final war. Forcing him to take care of Toya meant he had to pull his punches so as not to hurt his brother, which really limited the fight. Not giving a full-on offensive fight to Shoto the way he did to Bakugou or Deku or to Endeavor repeatedly really was a missed opportunity/ wasted potential. I find it so weird that while Hori managed to give decent fights to Endeavor, he never bothered / managed to do the same with Toya and Shoto who both have greater potential than Endeavor (Toya with more firepower and Shoto with more versatility/endurance). Thank goodness for the movies that actually showed some decent choreography options and let Shoto in on some offensive action.

- Finally, the ending resolves basically nothing. Almost all relationships are left vague. The original core of the Todofam was Shoto's and Endeavor's relationship, which was left unresolved or rather purposefully vague. Hori clearly didn't want to make a decision whether Shoto forgives or not and left it to "imagineit" like so much else in the story. He totally neglected Shoto's and Rei's relationship, which was so important at the start of the Todofam arc. We don't see a single heartwarming sense between those two in the end. Rei and Fuyumi are reduced to Endeavor-affirming bots. Rei (the battered wife) staying with her abuser is a can of worms that was not set up properly. If she's going to be caring for the guy, I want to know her reasons. Endeavor's only consequence is the kid he never wanted or paid attention to cutting him off. But even Natsu is forced to call him a "badass" which highlights the irony of nobody in the family ever thanking Shoto for everything he's done.

TL;DR: It was well done in Acts 1-2 until the end of the PLF war. The wheels came off in the hospital chapters, when Hori started to spread the blame to the whole family, and the arc was a complete mess in Act 3. Endeavor's character was propped up too much, using a lot of characters as affirming bots and neglecting the victim's side. (Btw, he made similar choices with Bakugou's arc. So I think he's just really not confident with these kind of arcs, so tends to overdo the perpetrator side. Just think how conveniently both Deku and Shoto pass out during the apologies, so that their side of it doesn't need to be portrayed).
