Maz Kanata

Maz? No. They couldn't do anything at all with her character in line with what we know of her from the movie. Cut/Deleted scenes not withstanding, we know she's force sensitive and serves two roles. Exposition and lightsaber handoff. So unless her special ability is premonition-related and the other is called "Words Do Hurt" and the animation is throwing word balloons at people, no. She's not fleshed out nearly enough.

Give them another movie or two to build her actual character beyond more than the one scene she was in, and she might serve a purpose. Until then, there are far more useful and in-demand characters to craft.
