Lol Back when using a jutsu involved lenghty hand signs and actually used chakra... Now people are teleporting with S/T, Using jutsu by putting there hands together or even OPENING THERE EYES, or creating rasengans the size of an elephant.
Its a classic problem, the same one bleach. You start off with everyone being perfectly fine, then you introduce a strong villain who takes it up a notch, and ofcourse the main hero and his friends need to also go up a notch to beat him, then a new villain comes in to take it up another notch, and again the heroes go up a notch to beat him... 12 villains later things have gotten out of control.
Its like when you see a sitcom with cute little kids and everyone is laughing, then 5 season later the little kid has a beard and mustache and things feel a little weird.. I wish for once there would be a series that thinks ahead and finds unique ways to introduce a villain other than just making him stupidly stronger/faster/OPer than everyone else... x__x
