You should never get too attached to a TV show. Eventually that thing you love is going to come to an end, and if it doesn't it'll be virtually unrecognisable from the show you fell for in the first place (hello, The Simpsons). It is particularly the case at the moment, as the shows that started this Golden Age of Television come to an end. Last year we bade farewell to the likes of How I Met Your Mother, True Blood, and Sons of Anarchy. The year before, it was The Office, 30 Rock, and a little something called Breaking Bad. Some shows will end things on a high, others a tragedy, and some will shoot for one but get the other, pi**ing off their fans in the process. What they have in common is that they all had to end, either of natural causes or cancellation, and in general the TV landscape is a little worse off because of it. That was no different in 2015, another stellar year for TV but one that saw some big hitters leave the scene. There were a couple of sitcoms that survived everyone by making it this far, a gory delight, and one of the best series of the last 10 years.
