I liked most of what Gifted did with Lorna in season 1. Felt most of it was better than what Marvel's written of 616 Lorna basically ever.
There are certain things I didn't like in it. Pregnancy right out of the gate is probably the biggest. I felt it was way too soon and without having explored Lorna more beforehand, ran the risk of derailing her - which it did from what I've heard of season 2. Season 2 of Wynonna Earp turned out to be an excellent model of how to do pregnancy well on TV. Another thing is that while the show did a great job of capturing a darker, edgier and sassier side to Lorna, I think it missed much of her heroic side.
When I say heroic here, I don't mean "colors inside the lines and follows the letter of law." I mean being a force for good who seeks to help as many as she can. Mutant Underground came off to me as more "one at a time underground railroad" in nature while Lorna would've been a better fit for me as loud, proud and visible, something the Mutant Underground held her back from. One of my favorite things from Gifted was actually the viral campaign before the show launched. It had Lorna and the others hacking a website to speak out against the "mutant cure" goal of the site.
Keep in mind that I stopped watching Gifted after Dreamer's death in season 1 because of how poorly it was handled. I grappled with that decision for a couple days. My fandom for Lorna said to keep watching as I liked her treatment and platform a lot, but my principles regarding character death and treatment of characters in general said to stop. So I don't really have much to say on what Gifted did during season 2 except to say what I've seen other people say about it.
