I'm with Si on this. On the whole S2 is pretty dire. It's what happens when you use all your material from the last 5 years in one series and then only have a year to write for a second.
Also the first series wasn't that good.
I agree, I enjoyed series 1, but series 2 has been rather shit and I have given up watching after about the 4th episode.
Wise choice, it actually gets worse towards the end.
