If you want to watch a good movie about TPB, consider TPB: AFK
It sounds like the new Pirate Bay series is a let down (although I have not seen it myself). But I do remember enjoying this documentary about the trio from 2013.
also, a darknet diaries episode.

Notably produced by the Pirate Bay guys
It mostly fiction to make it dramatic. I read the founders of the TPB weren't ask about the facts of the movie.
