So I'm not sure about you, but I see there being three actual main characters. Any other character will revolve around those three.

Dolores - I liked Farm girl Dolores. Wyatt was ok. The blend of the two was more compelling to watch. Especially when she brain-raped Teddy. You could see parts of both Dolores & Wyatt in that move. The general revolt of the rest of the hosts & the Man in Black/Billy storylines are ok. It was telling through that she was the first host to actually realize that the internal dialogue was actually her own consciousness.

Bernard - And in flashbacks, Arnold. I like this character quite a bit, because his compassion seems to be his cornerstone. Granted, he's had a completely different existence (life?) from Dolores or Maeve. He hasn't been killed (or raped) repeatedly, so that's going to factor into it. The fact that he/we spent a considerable amount of time not knowing his human/host status is a big deal as well. I would consider him the opposite of Dolores in the emotional spectrum. He finally realized who his internal dialogue is from.

Maeve - She's Mr. Hannibal Lecter's favorite! Which makes sense, because she's as close to human as possible (in degree of interactions with hosts). I would also venture to say that she would be the first one to actually feel emotion. Dolores didn't feel anger until she began to remember. Bernard didn't begin to feel shame until he remembered. Maeve felt love (for her daughter) well before that (as remarked by Man in Black).

It will be interesting to see where Season 3 goes. Dolores (in two bodies?) is out in the world. Will she feel the need to go home?
