season 3 was not in the same league as 1 + 2...
they should have stopped after the christmas special. The whole tone of season 3 was a bit off. it wasnt funny, more dramatic. I do not think it was the acting or the writing, which was exceptional as always, but something about the music and the direction...lots of really funny moments ruined by poor music editing and direction...first example the pops into my mind was Bryn at the beach, coming out of the ocean like Daniel Craig...should have been really funny, instead it was just there...
Its still better than most of the comedies the Beeb has put out recently...
