In the first season of the show the character was close to perfection. She was ranked as one of the breakout characters of the 2017-2018 TV season by countless papers. Emma Dumont really nailed it and carried the whole show. Her rapport with Esme Frost (aka Skyler Samuels) and Eclipse (aka Sean Teale). Lorna's relationship with Eclipse was really great the first season of the show and was everything that Lorna's romantic relations in the comics failed to be.
Calling the second season a disappointment would be an understatement. They effectively gave Lorna's role to a new character and Lorna's character descended into Eclipse's overly emotional baby momma territory. The first half the second season for Lorna is sometimes watchable. The second half of the second season for The Gifted Lorna is unwatchable and the epic ratings collapse in season two tells the story that it wasn't just me.
But, to focus on the good side the first season really showed how well a mutant activist Lorna can function. As a character Lorna works great when she has an overall goal and mission bigger than herself. This was true of The Gifted and its true of the comics.
Emma Dumont to this day still loves the character.
