I have read the entire manga series, each chapter and word.
And I cannot say there was a single arc or page I did not fully enjoy
The comedy is great.
The action is great.
Although exaggerated and unbelievable, the characters are enjoyable and funny.
The art is spectacular.
Really there isn't much to say. Just read it.
I enjoyed it even more than Z
The story is of Son Goku, little weird kid with kickass power doing kickass things. He isn't the most enjoyable character, but the situations he's put in utilise the small amount of character he has to great effect.
The side characters are the best part of the manga. Yamcha is hilarious. Krillin is awesome to watch. Tenshinhan is just all round cool. Bulma is a character you love and hate at the same time. Kame-sama (Master Roshi) is always a wonder to read.
The villains are usually wacky and enjoyable, but not scary or a threat. However this changes with the final two arcs, which will not be spoiled, but they're better than any content DBZ has to offer.
It's just an all round great manga. Read it
