When a clip from Disney’s forthcoming live-action film of The Little Mermaid was shown at the MTV Awards on 7 May, fans of the original 1989 cartoon declared on social media that they couldn’t see the appeal. Or, to be more accurate, they declared that they couldn’t see anything at all. Commenter after commenter complained that a supposedly magical and romantic scene between Ariel (Halle Bailey) and Prince Eric (Jonah Hauer-King) was so dark and dingy that they could barely tell what was going on. True, the scene takes place at night, but even so… “Where’s the light? Where’s the colour? This looks so dull,” grumbled one Twitter user. “Did all the lightbulbs blow at the same time on set,” asked another. It was the biggest protest against a film’s murky lighting since… well, since the last time Disney released a clip from one of its live-action remakes, Peter Pan & Wendy, two months earlier.
