I thought the season was well acted, shot and directed, but I agree with the excessive subplots. Hogarth's story is realistic and Carrie Anne Moss was brilliant but I didn't like it as a subplot because I'm not interested in Hogarth as a character. If her subplot was expanded into a (non-comics related) drama of it's own I could see it being brilliant.
I guess I'm also in the minority in that I enjoyed the first few episodes leading up to the reveal of the killer to be more interesting than what came after. It still retained it's quality after that but it seemed to retread the same emotional beats between Jessica and Her mother and never really moves past it. It just ends Spoiler.
