I was troubled by the title as it discribed the turtles as teenage. This is all very well, I don't expect to see their birth certificate as proof. However, as the plot develops they find themselves in 17th century Japan. Does this still qualify them as teenagers? This should be made clear in the title somehow. However, despite occasional unnecessary violence, it is an amazing film and sets the standard in RAT/PIZZA-based cinema. Kevin Clash as the RAT sage Master Splinter is incredible, and gives his best performance ever, even eclipsing his venerable work as the voice of Elmo in Sesame Street: Elmo's World - Wild Wild West. Stuart T. Gillard is also a genius when given a PIZZARAT script to weave his magic on. Don't get me wrong, his comedy classic Doin' Time (I pray for it to be released on DVD in the near future) is swell, but it just lacks something. That something is sushi-chomping rodant Master Splinter. The only other gripe about this film is how The Rat King character was overlooked, when expendable characters such as April O'Neil remained very much at the fore. Otherwise, file under:GENIUS!
