American TV sinking again?

I swear every year American TV networks release statements about how many great shows are due to debut in the upcoming Fall schedule. Most of them wind up stinking. And the few that are good, in my opinion, get dropped in the first 4 weeks of programming and you never get an ending/finale at all. "Community," "The Goode Family" and "Parenthood" look funny, so I'll look forward to watching 3 episodes before they're canceled!
