Re: TV shows you have gone off?
Office USA - Just became completely aimless after a few stellar seasons. The biggest example of a relationship stagnating a show.
Family Guy - It was never hysterical but it at least used to care about its characters and storylines and maintained a consistently funny tone throughout each episode. Now it's just a sketch show with poor punchlines.
If you can imagine Zidane's touch combined with Pirlo's vision and Roy Keane's will to win then you have some idea of the genius of Diego Maradona.
