Not only can The Simpsons not stop reusing the same tired villain but, to make matters worse, it is a character who the series originally killed off over a decade ago. I can see why people call The Simpsons tired. The animated family comedy has been on the air for 35 years and, in that time, it has aired over 760 episodes. It would be tough for any series not to feel tired at that stage but, although The Simpsons season 36 may change this, Ive been pleasantly surprised by how relatively inventive the shows recent seasons have been.
