I just finished watching The Little Mermaid and loved every minute of it. It may not be a popular opinion, but I prefer the live-action versions to the animated ones. I thought this movie was absolutely gorgeous, with some really nice additions to the musical score. (I loved Scuttlebutt!)
Halle Bailey was perfect as Ariel and the supporting cast (especially Melissa McCarthy) was very strong. The Little Mermaid was always my favorite Disney movie and I wasn't bothered by any of the changes or additions; they were barely noticeable. I thought they were well thought out and appropriate. I'm not sure why it didn't get more people into theaters but I hope it finds its audience at Disney+ because it would be a shame for people to miss it.
