This was, in my opinion, Disney's best live action adaption yet. The CGI was a bit rough in the beginning, but that's the only negative thing I can think of. I love the original as it was my favorite since I was a child, but they managed to make the live action have a little more depth. (No major spoilers ahead - it's a remake, nothing majorly new) We get to see more of Eric's longing to find the "mysterious girl", and how Ariel and Eric bond over their curiosity of the world and exploring. They added some new songs and I liked them, especially Eric's. The Broadway style casting (aka colorblind casting) of
all of the characters from the merpeople to the kingdom was a good choice. Go in with an open mind and you might just enjoy it!
