David Bianculli

The fifth season of Dexter, which premieres Sunday night, is better than ever, says TV critic David Bianculli, who calls it "one of the most inventive and exciting shows on TV."

Today is the official start of the 2010-11 TV season, and for the first time in many years, all of the major networks are unveiling most of their new and returning shows in a single, event-packed week. Our TV critic, David Bianculli, is impressed by the effort -- but not, this year, by the results.

The new series is set in Atlantic City in the 1920s -- where corruption and organized crime run as freely as the banned booze. Critic David Bianculli is impressed by the cast, which includes Steve Buscemi and Kelly Macdonald, and says the emotionally intense drama is worth adding to your must-see list this fall.
