Some shows leave audiences wanting more. The retro Freaks and Geeks, which featured high school kids who actually looked like high school kids, and the mid-'90s teen drama My So Called Life, memorable to me for featuring Buffalo Tom, are two rookie-season cancellations that have received a second life in the DVD format. Other shows overstay their welcome. They leave us wanting less. We suffer, but so do the actors whose careers are destroyed through something known as the Ziering effect. Named for 90210's Ian Ziering, the thirtysomething actor who passed himself off as an 11th grader, the Ziering effect's victims include Todd Bridges, Robert Reed, Shelley Long, and other type-casted television actors who struggle to find work after primetime stardom fades.
