Kill off Rosita - weak character, weak acting
Irrelevant, useless, no character development. She serves no purpose other than to be there.
TWD premiere really showed how little faith they had in her character and to a degree, her performance. At times, she seems almost bored or annoyed, rather than grieving, aside from a few shocked teary faces around Negan. She also seems to pout a lot. Ever since she joined the show, she felt out of place with the other cast. Her monotonous Hollywood voice and cartoony appearance, completely out of place with the gritty rural Georgia environment.
She was in a relationship with Abraham since season 4, but it felt like she was rendered impotent as it focused on Maggie and Sasha's grief more. Both actually had lines (something Rosita rarely gets). Maggie lost her husband and Sasha lost a boyfriend, but Rosita was with Abraham longer. On social media, I'm seeing discussion about Abraham and Sasha's romance, but nothing about Rosita. It feels like her character was a useless dramatic device for a man to realise he wanted someone else instead... to have kids with?
So what's the point of Rosita? Doesn't seem like the writers are getting rid of her any time soon either. I don't really see any interesting character evolution coming. She didn't start out weak and become strong like Carol or Beth, she isn't a dynamic member of the group like Michonne, she hasn't lost everyone she's loved like Maggie or Sasha. She doesn't have an interesting history on the show and a distinct personality like Tara.
She needs to go.
