I didn't know about it until your post. So I watched some clips. It was, as you say, okay. Feels like they've taken some aspects of the first run, like Mitchell's hysterical reactions, and just gone with that.
I'll hold off on having an opinion until I've seen some more, Mitchell and Webb is really hit or miss with me. The first sketch show series and their panel show appearances together are legendary. Peepshow sucked something awful.
