Thirty-four years ago, Disney released what would go on to become an American classic: the animated Little Mermaid, its titular role voiced by Jodi Benson. On Friday, the half live action, half CGI Little Mermaid remake (now starring Halle Bailey) opened in theaters—though critics seem to think that it hasn’t been properly updated for the new century, or changed enough to warrant a reboot.

Most of the plot remains the same: a curious, adventurous mermaid princess wants nothing more than to become human and explore the world above. But some mostly minor tweaks do remain: the villain becomes an octopus rather than a squid, a new royal character enters the picture, and a few new musical numbers crop up. Read on for 10 tweaks to the watery tale.
