It's early days, but she's utterly abhorrent so far. It doesn't bode well if she's the main reason to watch the show!
I only watched the first season for now and I have to tell you that these characters continue to be assholes. There are developments, but they continue to make deplorable decisions throughout. If a show focusing on the actions of horrible people bothers you, then you probably won't enjoy it much.
However, even though they are shitty people they are not shitty
characters. Almost all of them are written in ways that make them interesting and entertaining as hell to watch, which imo is way more important than them being good people or likable on a personal level. It's a very fun and addicting show.
