I also binge watched it over the last couple weeks. It gets better and better and each episode feels like it could be a season finale with so much happening.
I just caught up with season two. My issue with the show is that it feels like two different shows that got merged together. I like the white house story lines, but Olivia's coworkers drive me bonkers.
I got totally hooked recently as well. I'm all caught up and, while I love some of the later drama, I miss the D.C. scandal story lines that don't revolve around Olivia.
I had the same experience. Tried it back in October maybe on Netflix, just the first couple episodes and was "eh." But then I went back to it a month later and was instantly pulled in.
