We've just started the 4th series and it shows no sign of letting up in the quality of writing and acting. This, together with "The Brink" have to be the best things we are currently watching, although our second run through "Madmen" is good (we haven't seen the last series but are now on three) as is the final series of "Midsomer Murder", which again are new to us.
We've cleared "Arrested Development" which should have stopped at series three and "Modern Family" that used to be so good is now utterly awful. We have now stopped at seven and it will take a lot to view the current series. Talk about flogging a dead horse.
