dbgtsuxballs (Level 3)

as by my name you can tell i hate the dbgt for many reasons. 1st kid goku wtf. 2nd pilaf is dead from super buu's human extinction attack and dende only wished back good people. 3rd why didn't they use earth's dragonballs to wish the black stars back to earth and to fix goku. 4th if pan couldn't go super saiyan then how can her grandson who is only 1/6 saiyan. 5th goku leaves his family and friends to train with a dragon who is over 9000 times weaker than him (as proven in the king piccolo saga when piccolo kills shenron it implies that goku is stronger since he kills king piccolo). 6th piccolo's death was in vain since the writters forgot that he fused with nail, therefore, making him a different namekian than the kami before he split with piccolo (so the black star dragon balls should never have existed). 7th majin buu didn't have to fuse with uub to fight baby vegeta, they could have teamed up and baby wouldn't have stood a chance (i know mr satan told buu not to kill anymore i don't mean kill baby just make him leave vegeta's body like what goku did). 8th (and last even though i have more) everyone is weak except goku when in dbz everyone was strong. 
so in short dbgt isn't a direct sequel to dbz since there is continuity and it sucks

goku didn't need to become a kid again, there were over 9000 plot holes and mistakes (like how piccolo's suicide was in vain since the writers forgot he fused with nail before kami and how krillin couldn't be brought back by shenron even for old times sake since he was wished back in dragon ball) the black star dragon balls were a waste of time since they could use the earth dragon balls to wish the black star dragonballs back to earth and to change goku back into an adult, it might not have even taken place in the same version as the last two series did, it made dragonball evolution look like an oscar winner, in the end goku leaves his family and lets everyone he loves die of old age without him being there.
