First of all, before I bash Dragonball Z, I did keep in mind that when I watched the few episodes I did see, I wasn't expecting this to be a "high class" anime.
With that said, I didn't find DBZ amusing or exciting, give or take a few ridiculous scenes. This is NOT an anime for people who don't like having their patience tried, since this anime is rife with overlong fighting scenes and redundant pervert comedy. I recommend this anime only for easy to please people.
Finally, it's worth noting that I'm one of the extremely rare anime fans that never saw DBZ during my youth or teenage years.
