I've slowly been watching it this year. I'm just up to season three. I am also watching it in chronological order, which is slightly different than the order in which they aired. I have a print out of that order and marking it off after each episode.
From what I understand I am just getting to the point it really picks up. It's a mixed bag so far, Definitely some clunkers early on, but it's improving and decent. When it's good, the 22 minutes just fly by. I haven't been completely enthralled to binge mode by it yet but as I said, apparently season three is when it's meant to get much better.
