I think all 3 shows are good. However, I do agree with Aoi. There were too many characters and they all come together to transform once, and that's at the end. However, I still say the music from the show is awesome. I would even suggest, even though it may be tough, to watch all of Gransazer. Though it starts fast and slows down in the middle, it picks up in the end and has an awesome finale. Why watch all of it? Because in Sazer X, the 3rd/final series, they have a team up between all 3 series. Watching all 3 and then the movie will be really rewarding in the end.
