I, unlike a few others I have seen in reviews, do like Love as a character. I like her as an actress too, she was also great in The Haunting of Hill House. I do enjoy the complexity of the characters and how "evil" is not so black and white. It's normally hard to root for a sociopathic and psychopathic character but with this show, I often find myself empathizing with Joe and sometimes even rooting for him.
I do find one thing is true in all of these reviews I am reading. This show is starting to feel very much like it is trying to be Dexter. In this episode specifically, the dinner scene was oddily familiar not only from Dexter's opening theme, but also how Dexter used to kill his victims. If you don't understand what I am saying, watch the episode. You will get it right away.
I am only now finished the second episode of the second season so I can't speak to how the rest of the season will be yet, but this episode specifically was good and kept me watching (and I have pretty bad ADHD) without losing interest once. However, it wasn't amazing. It wasn't brilliant. But I can see how it's just laying the foundation for the rest of the season. Looking forward to seeing what 'You' has in store.
