I love DBZ threads
The series is obviously a classic, but didnt quite reach it's full potential; it became a bit stale and predictable. That Buu saga was just
. When a being can just constantly keep regenerating itself.... that get's old after awhile.
They underutilized certain characters, mainly Vegeta and Brolly(I'd throw Piccolo in, but he got some shine during Dragonball). Vegeta should've had at least one epic win by himself. And Brolly should've had his own arc.... in fact they could've found a way to incorporate him into the Buu Saga. Have Brolly coincidently come to Earth looking for "Kakarrot" while Buu's reeking havoc. Have Brolly and Buu have an epic global fight that eventually kills most of the people on Earth while the Z fighters look on like
Brolly turns into his ape form and beats Buu, and the Z fighters are like
. But then they realize that Brolly really came there to kill Goku
and let the fukkery ensue. Goku vs. Brolly, Gotenks vs. Brolly, Mystic Gohan vs. Brolly, Vegitto vs. Brolly... etc.
Have Brolly blow up the Earth and all that shyt. And finally kill Brolly with Vegeta's Final Flash, Goku's Spirt Bomb, and a Kamahamaha from Gohan all hitting that nikka at once. I'm sure the creators could write it better than me, but the series was mainly centered on the power of the Sayains, and an epic battle with the 4 strongest Sayains in history would've wrapped up the series nicely IMO
Buu was lacking as a villain because he really didn't have any purpose; no agenda. Brolly's lifelong hate for Goku and his desire to destroy everything Goku held dear would give him more depth as a villain and allow a better storyline to flow IMO.
