There are things I'm concerned about, things like:
Why Naruto's using his mother's (Uzumaki Kushina of the whirlpool country) surname Instead of Namikaze Minato's (Minato the 4th hokage, his father).
Why minato chose to seal the kyubi inside his own son, giving the key to the seal to jiraya, and asking jiraya to make sure naruto perfects the rasengan.
Why Minato sealed only the ying half of the kyubi's chakra, leaving the yang half for Naruto.
what happened to Uzumaki Kushina?
how come Jiraya's students become so freaking strong?
