While a lot of us here have discussed and others have seen the recent live action TETSUJIN 28 movie (now available on DVD from Geneon Entertainment), and whether you thought it was good or a bomb, I'd like to point out the extremely impressive animated series produced in 2004. Directed by Yasuhiro Imagawa (GIANT ROBO: THE ANIMATION), I urge everyone who loves anime and those who love Old Skool manga (as well as those who love GIGANTOR) to check out this amazing series which is available on R1 DVD from Geneon Entertainment (with a great score by Akira Senju).
