I really quite like it. I am sometimes struck by the time frame though, for example, in the last episode Frank said to Zoe that he hadn't seen her for 3 weeks or something, so I imagined that roughly 3 weeks had passed since the last episode. But then, it turned out that Russo had been sober for a year... even though the 'within-100-days bill' was signed at the start of the episode?
Though, i'm probably just missing something, and it doesn't really take away any enjoyment. I do like the show, and I sort-of root for Frank, even though he is a bit of a dick. I did find both his 'Fail' TV interview, and the whole brick speech at the end of that episode a little out-of-character, two extremes which I didn't expect him to go to.
I didn't like Frank's wife at first, I guess mainly because you see her sort-of cheat on him before you really see what Frank is like. Now I find myself sometimes really liking her, then feeling quite off about her within quick succession.
Zoe is an odd one. I really liked her until recently, especially with the whole 'on the phone to her Dad' thing, at the end of the last episode that I watched. About the only truly likeable character is Russo, providing he doesn't hit the bottle or the drugs again, because despite his insecurities, you can see he is a decent bloke at heart.
That is no negative though. I think the best type of shows are the ones where you are interested in the characters, despite having serious flaws on show.
