Well, I finished the 1st season and loved it. I'm almost halfway through the 2nd and it's still good but I hope it gets better. I think I like it a tad less because if someone dies, you figure they'll just go back in time yada yada yada. Or not even, they'll be saved after a shank in the gut in the next episode by someone who somehow was surprisingly ''there'' AND able to sew them up in a jiff. And while Klaus was slightly annoying in the first season, you could still feel for him knowing why he was that way, that it was a kind of a front. Now...
As Chalice said, I really like some of the details, like the opening scenes with an umbrella. I think what I mostly love about the series are the stories about the dysfunctional family and how the siblings came to be the way they are. Even if they are two completely different series, it kind of reminds me of The Haunting of Hill House, which I loved.
