The only thing wrong with Better is that the BBC pitched it as "the new Happy Valley". And because they did, the show got a weird audience and critical reception.
Line of Duty is incredible, right? But if someone promised you Happy Valley and you sat down to watch Line of Duty, I don't think you'd like it much. That's what's happening here.
This isn't Line of Duty. It isn't Happy Valley. Better is in a category of its own, and it stands as tall as either of those shows do.
Leila Farzad is astonishing, like she is in everything. But this is a brilliantly written game of chess that has you emotionally invested in all the pieces on the board.
You haven't seen this character arc in a cop show, and you haven't seen this story in a drama before.
(Also, I don't know how you even begin to write a second season after that ending, but my god do I want to see it.)
