For the first series of a comedy show it's surprisingly good. The rapour between the leads is great and they're are a lot of good laughs. Not everything lands but it's one of the best new comedies I've seen in a long time. I've laughed out loud at least once per episode and had a beaming smile in most episodes as well.
Give the first two episodes a go if you're not sure. The first episode is probably the weakest so that's the best way to get a feel if the show is for you. It can be a bit predictable at times but that isn't really a bad thing and so I hope they make more of it! It's certainly better than the other recent comedy pilots on the BBC.
