I saw it opening weekend (on my 37th birthday) and thought this film was very cool! I'm an animation nut and have enjoyed the Turtles in their various incarnations. I think this film was the best of the four! I watched TMNT 1 earlier today and I'm watching part 2 right now. I saw all of them when they were first released in the theatres, but I don't think time has been too kind to these movies. Still, they are quite enjoyable for what they are. I hope we get an animated sequel to TMNT 4.
