Ah...Dragon Ball Z...my deep dark secret. I used to watch it all the time when the Freiza Saga began. It was my favorite story arch of all time. But when Trunks came, I just felt the magic vanish. What? Time Travel? Please... however, the movie conserning how he came to the past was nice. But that was it. Also, for DBZ, the power-ups were pointless. I remember in the end of the Cell Saga or whatever, Goku was powering up for a Spirit Bomb, and he was powering up, for what, 5 episodes? Maybe 6? Some rediculous time period anyway

But in the original series, when Goku has a power punch, he did it in 5 seconds tops. That's it. No great wait or anything. It kind of stunned me at how quick it was.
Speaking of the original series, I watch it all the time on CN. Mondays to Fridays at 8:30pm. Very good stuff, like showing how useful Mr. Popo actually was in the original series. In DBZ, he just stands there doing pretty much nothing. In DB, he was defeating Goku in hand-to-hand combat.
Maybe some time in the future I'll watch the uncut versions of DBZ, but for now, I'm content with the original series playing
