Teenage Mutant Ninja Turtles (CW)

Over the years, the TEENAGE MUTANT NINJA TURTLES have had many incarnations. Their comic book origins led to their first animated series in 1987 and a few live-action movies in the early '90s. This show, which premiered in 2003, is closer to the original comic books. The animated series features the amphibious foursome -- Leonardo (voiced by Michael Sinterniklaas), Michelangelo (Wayne Grayson), Donatello (Sam Riegel), and Raphael (Frank Frankson).

The animation makes the show less irritating than the live-action films, but only barely. The amphibious brothers still talk like southern California skater dudes (except one who, strangely, has a New York accent), and are still differentiated only by the color of their eye-masks, making them virtually indistinguishable to adult viewers. Taking its pacing and approach from Japanese anime (though not its animation style), TMNT is quite violent, filled with nunchucks, throwing stars, swords, and many, many fight scenes punctuated by flashes of blinding light and characters flying sideways through the air to land crippling kicks. Though the Turtles are ninjas, studying under a sensei named Splinter (a giant rat, natch), they're surprisingly materialistic and Western in their overall thinking.

The program's overall messages purport to be positive ones -- working as a team to overcome evil, for instance -- but the underlying themes aren't as encouraging. The brothers use violence to achieve their goals, unapologetically chopping, stabbing, maiming, and beating their enemies to within an inch of their lives; their friend Casey (Marc Thompson) has a cousin who shows up with a machine gun in order to steal an inheritance (to pay off his gambling debts!); one of the Turtle brothers is brooding and uncommunicative for no real reason; and so on. This is a show that will definitely appeal to younger viewers, but because of the violence, a preview would be a good idea.
