This is right, actual seasons of DBGT are 3 now, and all the story, the original Japanese version has 17 seasons of DBZ, but it is more detailed. Also if you go to Let me watch this or 1channel.com I think it called now, you can watch the entire 3 seasons of DBGT and all 17 seasons of DBZ Note: DBZ is all in Japanese in this) I know, makes no sense. But ok.
