Excellent. BBC Scotland has been repeating one of the later series recently, and it's whetted my appetite for more. I enjoyed the Christmas special, however it was interesting to compare Rab C with more recent BBC Scotland comedies like Chewin the Fat and Still Game (both of these have been networked around the UK as well, although not normally in the peaktime slot they get when screened on BBC1 Scotland, normally on a Friday night). There are some excellent writers and comedy performers in Scotland at the moment, and for me it is the existence of that talent, rather than anything lacking about Rab himself, that made Rab's Christmas special look just a little less fresh than it might have.
I thought they made some great gags out of the fact that BBC Scotland has now moved more or less onto Rab's doorstep though.
