When Mach Go Go Go debuted in syndication in the U.S. as Speed Racer in 1967, the series had been extensively re-edited to excise much of the violence. These edits cause some continuity problems: in "Girl Daredevil," new tires appear on the Mach-5 between two scenes, and a villain steals the car, although it was out of gas minutes earlier. As the exploits of Speed, Trixie, Sparks, Spritle, and Chim Chim remain a touchstone for fans who grew up watching them, members of Gen-Y are unlikely to be troubled by these awkward moments. Unrated, suitable for ages 6 and older: cartoon violence, tobacco use, minor ethnic stereotypes --Charles Solomon
