I used to Mazinger Z dubbed in Arabic, which I had no clue what was being said, but thoroughly enjoyed the action spectacle of giant robots battling. Having seen this full length animation with English subtitles, I was able to enjoy it even more. The animation was more slick and had a 3D feel, unlike the original series, which were hand drawn. However, the return of the original Mazinger Z to save the day was what made this movie great. Furthermore, it managed to retain the tone and action of the series, despite having triple the run time of the cartoon series. It was great to see the old characters, and old mecha monsters in action. It is also great that they are improved versions of their original selves. The action scenes are spectacular, and it is great that I finally get to see Dr Hell, and Duke Ashura battle against Mazinger Z. All battle scenes are spectacular, while the drama surrounding Koji, the Mazinger Z pilot is provided to provide more character motivation. However, the movie does not get mopey, but it more than delivers on action and spectacle. A must see for fans of giant robots in action.
