TV: The Official Fall Season Begins

The Big Three (ABC, CBS, and NBC) come into the official start of the fall TV season with a slate dominated by returning shows. CBS's comedy lineup welcomes its first new show, Worst Week. With volume three of NBC's Heroes also beginning on Monday, along with a new season of "Dancing With The Stars" on ABC and Prison Break with a head start on Fox, here's hoping it's not the Worst Day too.
