Probably because it was edited i mean i have most of all the original stuff and its excellent man no BS powering up for 2 episodes,skipping fights,cutting out all the violence or stopping Master Roshis perverted side that is one of the best things in the show!
I remember when i was in spain i watched trunks chops mecha freiza into bits,blows him away and then he blows his dads stomach blood and all.Now in the edited stuff(when i came to australia)it didn't show any of the violence it makes the show look bad man.
I just watched parts of dragonball evolution on youtube and it makes me sick they did it on the cheapest budget and probably made a heap amount of cash on it i hope FOX drowns in a pile of all the worlds ****.
