"Dragonball Z" might be one of Japan's most well known and famous animés, but I believe that its reputation is overrated, even for its time. There are a number of aspects I could cover in order to explain why I don't like it. The never ending, ever growing power of the characters. The weak plots don't help either. And the insanely ridiculous fights are also another reason not to watch it. Also, if you haven't seen it, you'll need to see "Dragonball" first in order to understand "Dragonball Z".
My advice: don't bother watching this.
