Put a list of Ursula Le Guin works on a wall and throw a dart at one of them. Don’t know which one you threw a dart at? That’s okay, because absolutely none of them have gotten good adaptations.
The only exception, extremely ironically given I’m saying this, is Tales of Earthsea. The first half is alright but I guess they lost their train of thought during the second act (their words not mine) and it became a Legend of Zelda story. Still not terrible though, I can’t understand why people hate on it when the same people love Ponyo.
