This version of Reideen is a terrible disappointment. The story is good, the 2D renderings are good, characters are good and the Computer generated Reideen and mechas look beautiful. Unfortunately, in action scenes the CG looks like something produced in a school project. The Mechas look beautiful but the movements are so slow and so simplistic it looks amateuristic. Imagine everything in slow motion. Imagine those kids cartoon where they use CG and the movements are choppy and simplistic. Now imagine those horrible kung fu movies where the extras are fighting, slow simplistic badly coordinated moves. That is Raideen fight scenes, the mechas look beautiful throughout but the action is slow and always happens in the dark (I guess to mask any CG defects). At first I thought I had accidentally slowed down my player then I thought it was the intro 1st fight scene effect (to show the awesomeness of the Reideen and CG) but it never sped up. I jumped to different episodes and it was still slow. it was watching it at 50% speed. In fact watching Reideen, it is perhaps the first time watching mecha anime that I did not want mecha action scenes. The action scenes basically kills the story. It slows the story down and looks amateurish. I say give this a miss, really cannot recommend this new Reideen.
