naruto actually mastered rasengan but doing it without the shadow rep which i thought was pretty cool in the fact that it was red at first then BAM blue rasengan

heres one thing i dont get, like how the BIG black sphere is just growing and like solifies even though naruto and sasuke stopped their attack look at each other for like who knows how long then attack and its gone... i think that is totally ridiculous

Naruto did not master the rasengan......the only reason he could do it with one hand is because he was Kyuubi lvl 2. Thus his powers all enhanced such as chakra control which is used in doing the rasengan. Normal Naruto and Kyuubi lvl 2 Naruto are completely different.
