This is probably one of my favorite shows and I uphold my 10 stars rating after watching the second season.
Top of the lake is a slow burner, with unique characters that are very flawed and human. If you let it, it can get under your skin and leaves you wondering about the heavy issues, that it dares to deal with.
For example, the second season's main theme is motherhood, abuse in relationship and exploitation of a marginal group of people (sex workers). I think you wouldn't expect the ending which is a quite unique twist, but I won't say more.
This show is also quite good at playing with your expectations and turning them upside down, which is the hallmark of good storytelling. The female characters are quite prominent and well written, without being obnoxious feminist champions. They feel real and very relatable. The antagonist is also very good, I was worried, that the new antihero will be only a pale shadow compared to Peter Mullan, but oh boy, was I wrong!
I can only recommend Top of the Lake, it's not your typical good guys vs bad guys show. It's about people who collide with each other, have interesting story arcs and face relatable problems under unusual circumstances. Don't listen to people who watch half an episode and come here to write a "review".
