Yea, people are complaining about how they hate her - but I'm pretty sure that's the point. I don't like her either, but I think they have something interesting planned.
Really liked this week's episode, and at least twice I was surprised by where they went with the storyline. I can't understand the complaints about too many characters or story lines - if you expected Castle or NCIS, that's not what this is. The show is called Gotham, not Gordon, or Batman, or Penguin. The variety of characters and stories allow for more surprises.
I also love the ties to the Burton universe. Obviously Selina is a Pfieffer look alike, but she has the attitude down as well. And Joker? Yea, that was heavy on the Nicholson, although there was a darker edge in there as well.
I like that they tie things together over the course of many shows too, like the Doll Maker coming back around as a major plot point a dozen episodes later. That will keep this show interesting over seasons, rather than some simple villain of the week motif.
