I only watched the first episode and really didn't like it. I strongly hate celebrity cameos. It felt like a Family Guy "holy crap, you're Hugh Jackman!"
The first episode was by far the worst episode of the season. Honestly the first 3 are all kinda meh but it picks up after that. The most recent episodes all feel very similar to s1. It feels like that are making a concerted effort to return to their roots, but still had some episode in the pipeline they couldn't change which is what we see at the start of the season. Its only a few episodes tho so who knows if it will stick.
