First off let me just say, as far as comedy goes it really dosen't get any better than this. The reason for a Three Star is not a reflection on the item itself but the suppler... ie: Universal Studios. Cast your minds back to when series One and Two came out, just about everybody rushed out and bought them.
A short while later low and behold Universal reissued them again with one differance... they included the 2011 Christmas Special. I like many wanted this particular episode but to obtain it had to buy the whole lot again, and either give or sell my first purchase at a loss.
Well guys, Universal are up to making even more money out of us by (surprise surprise) doing it again with series Three. This set contains only six episodes on two disc's and does not include the two 2012/2013 Christmas specials... I think you'll find in a couple of months (when the sales slow down on this series) along will come the box set containing all the Christmas specials.
So my advice to you all is to simply save you money... and try to be patient for the complete eight part series as show on BBC television. Oh, and incidentally BOC pictures have confirmed a forth television series later this year, and if that too has a Christmas Special or two, we'll be going through all this again.
