2 part answer; a show could do everything they need to in about 5 seasons.
How many do I want? Depends on the show but I'm fricking selfish
Give me more. I hate that BB is ending. I hate that The Sopranos and The Wire ended. I'm still pissed the arse fricks at HBO screwed over Deadwood after 3 glorious seasons.
I didn't think House needed to go either, but at least it was 8 seasons. Mad Men looks to have at least a couple more and I'm happy.
If it's a good show, let it continue. Better than rolling the dice with the crap put out more often than not.
eta: I will say this and definitely not to pick on Fringe, but I think it had run it's course and ended maybe even a season late. Still dug it though.
