i don't mind if you say the story was not good, everyone has their own opinion. remember, this is fantasy, so anything that surpassess reality can happen. i mean, The Planet's not necessarily have a gravity pull as strong as our Earth. that's why people can jump really high. it's just the same as every other anime, if you're saying that the fighting scenes are shit, you're saying that dragonball's stupid because character can fly without any help, or that naruto's crazy because no one can split into 5, or inuyasha's dumb because demons don't exist, or one piece is shit because nobody gains superpowers just because they eat a fruit.
