I really enjoyed Season 2. I liked Season 1 as well, but Season 2 is sticking with me a week after finishing it. I routinely dislike period pieces and romances, but it's so smartly written, well acted, and so beautiful to look at. The glow coming off the Sharma girls (especially Kate) was so beautiful!
I hope I didn't miss something, but I loved that it left it open whether Kate had a past, or at least was a bit more worldly about men. To that, I say, good for her. I don't think it was suggested she was virginal or doing it with Anthony somehow "sullied" her - it seemed her flashbacks may have just been because she was with someone amazing. I thought that agency suited her perfectly since she's older (ancient, practically!) and smart.
