Saw Mermaid last night. Honestly didn't really find anything special about it, but also didn't find much "wrong" with it either. The performances were fine, standouts probably McCarthy and Diggs.
What has frustrated me about these remakes is that the added runtime doesn't expand the world or refine the storytelling, but rather just pads the runtime. Too many instances of bad writing in this that it was frustrating. That being said though, it was "serviceable" but nowhere near the live-action remake peaks of Jungle Book, Aladdin, BatB, Cinderella, Cruella imo.
