Stick with it. It's good. Most long form crime series pad out their stories with stuff, like the so called angry feminist element you speak of. However, misdirection is a key part of these dramas and the padding is the misdirection. While I don't want to give any spoilers, the misdirection is there to keep you from solving the mystery too soon. What would be fun in watching if you guessed right off the bat. Season 2 of Bron / Broen made good use of this with various plot elements. Same goes for the Killing.
At the end of the day this is still just a crime drama, just with characters a bit more wacky than usual.
