Here's a pretty nifty little fan-made film in which some gritty Foot Clan goons get the grit beat out of them by a gritty ninja turtle. Gritty.
I would love to see the Turtle franchise rebooted. The animated film, TMNT, that came out several years ago was a lackluster attempt. 2010's made-for-television flick, Turtles Forever, in which the modern turtles join forces with the 80's turtles and the black and white comic turtles, was actually quite entertaining though.
