As for the Sopranos. It did get pretty annoying when they kept introducing a character who, they had forgotten to tell us, was very important to Tony and the family. Just so that guy could get killed. Mainly Ritchie, Ralph, and the other Tony. All of that aside, the second half of season 6 was some of the best of the series.
HIMYM: I bet they would reconfigure this one if they could go back. The premise didn't survive the show becoming a hit, plus they made Ted the weakest character.
The real answer, but I was still pretty young: family matters. Good grief they had Urkel creating time machines and shite.
I'd also say Boston Legal, the writers seemed to phone it in once the show kept getting put in to limbo of not being picked up every year.
