Eternals: 24 WTF Moments
17. Thena Gets "Mad Weary"
One of the weirdest and most superfluous subplots in the movie is Thena (Angelina Jolie) suffering from "Mahd Wy'ry," basically a form of dementia for Eternals, who after living for potentially thousands of years can find their memories beginning to falter.
Though Mahd Wy'ry is ripped straight from the comics, it's not easy to take this subplot seriously both due to how utterly silly "mad weary" sounds spoken aloud, and the fact that Thena's condition conveniently only flares up to drive a wedge between the Eternals when necessary.
The idea isn't uninteresting, but given that it doesn't amount to much more than Thena occasionally getting into fights with her fellow Eternals and them arguing over what to do with her, it could've easily been left on the cutting room floor in a movie that's already brutally overlong.
