Maz was fine in TFA, but to me she felt unnecessarily shoehorned into TLJ. I really can’t see where she’d fit into this larger story. To me, it cheapens the weight of the character from TFA.
Side note: As I’ve said for a few years, when you have a woman this beautiful and talented in the cast - don’t cover her with CGI. Find another role for her and get someone else to read for the drawn character.
