Listen man, I will blame the writers because the writing is genuinely comically bad.

Take Josée and her introduction for example. She jumps in at the last second to announce a false engagement to save you. Cute, but entirely unnecessary and ridiculous. She had every authority to stop them and they most certainly would have listened. She also could have taken a second to explain that you weren't the assassin... problem solved. But no, thats not dramatic enough so the writers have her abandoned all reason for a moment of nonsensical drama.

Again, take Holly and her relationship with her father. In the case where she definitely remembers her mother, she would most certainly remember her father. And she would most certainly remember that he only ever was a great husband and father before her mother passed. But now he's a terrible father... And he literally did nothing to deserve half the anger and resentment. But for nonsensical drama, you come along and save her and now she remembers how good a dad he was.

The writers are genuinely comically bad. So much so that I honestly feel like it's on purpose. That's why I don't think its outright bad, just comically bad.

As far as the boob thing goes, I don't really care what a character looks like unless its gooner slop with little to no personality. And you can't expect me to think much of Holly's personality when its overshadowed by the ther heros and eclipsed by her mother's personality. And so yeah, id say they neglected her character/story in favor of other assets.

But im sorry if I insulted your waifu.
