High-profile changes in returning shows --Two and a Half Men and CSI: Crime Scene Investigation — offer the most excitement in broadcast TV this fall. Critic David Bianculli says the new shows mostly disappoint, though you may be intrigued by Sarah Michelle Gellar in CW's Ringer.

New seasons of Curb Your Enthusiasm and Torchwood premiered over the weekend, and three other cable shows return to prime time starting Wednesday. Never mind that it's the height of summer — TV critic David Bianculli says this week will be a TV fan's Christmas.

A new version of the British sci-fi series and a new season of the Larry David comedy begin this weekend on Starz and HBO, respectively. TV critic David Bianculli says while the broadcast networks are taking it easy, these competitors are serving up excellent, unusual television.
