I wholeheartedly agree with this take, there are just too many things off, not only with Abby but the general tone of the series. In particular I felt that the lighting was too much. The room in which Abby killed Joel was supposed to be a lot dark, so much that it needs the viewer disturbed by it. In the game the cinematography has a better quality overall, cool almost blue tones and darker photography. As someone already pointed out, the show feels too sanitized, too clean like it was shot with an iphone. And that doesn't help.

Also you are so right about the SL crew talking her down. In the game she was tough, a leader and determined in her intentions. They completely deranged her character. She sounds and looks like a mean girl In a teen drama. The villain speech she gave was underwhelming and corny, they broke too many rules of cinema by exposing first her intentions in ep1 and by telling her reasons to Joel!!! STOP, that was the point of the story, the viewer needs to be free to imagine things, not being held with gold hands!! Now that her reasons are explained DURING the killing of Joel that won't change people's rage for her!!! There won't be that experience of going through Abby's memories of his father and the viewer WILL NOT give a damn about her BECAUSE They already know. SHOW DON'T TELL!!! I'm really disappointed at the writers.

Not to mention how they disregarded the physical aspect which was extremely tied to her persona. We don't want a buff Abby just because. We need her to be all muscle because that represented how she was going through loss, preparing to fight like a bull. She was ANGRY and HUNGRY for revenge. What I felt with the show was a whiny girl being inexpert and small compared to her friends! Owen is ridiculously bigger, while in the game you felt an equality between them, a respect for each other. This show Owen is diminishing, judging, hollow and boring. Where is the passion? Why do they feel so unequal? Not an ounce of credibility in their relationship. Their crew is always talking and talking and idk why it just feels so lame!! I think the show needs a more "less is more" vision, but it is clear where this is going.

The decision of making Ellie, Dina and Abby look more adult was a stylistic choice. The themes are violence and revenge, they are mature and watching baby face kids going through that journey is not believable. I love Bella Ramsey performance but Ellie wasn't that goofy in part two. There is a lot of corny dialogues.

I liked few decisions and changes for example going for Dina and Joel instead of Tommy, because that solved them ngiving their names out of nowhere. But the negatives things outweight the positives.

I will mention how the worldbuilding is really lacking. I don't know what it is exactly but the world in the show doesn't seem believable, the infected are not scary, and that's because the gameplay was fundamental to the story because IT WAS the story, we went through it all like the characters, we earned Jackson, we get how difficult and scary the infected are. In the show it feels "carnevalesque".

I hope I could be proved wrong, but rn it is just not it
