The Simpsons were great back in the day, but eventually a shiny diamond gets scuffed and it's shine begins to fade. Alot of the newer episodes of Simpsons, and mabye also Family Guy, have gotten stale in my eyes. South Park have actually gotten more proffesional, with more relevent plots and jokes, American Dad is new, and cracks me up sometimes. Futurama is one of the best, because it is an original setting with original characters (Who here doesn't find Bender to be funnier than Homer). Every series does have to die sometimes, 441 episodes is a great achievment, if the series could improve, I might change my views, but There is not much else to do that has not already been done.
