'that's why I've grown out of anime' and quit it. And I couldn't blame him.
My favorite argument for this is always:

"uhum, yet you watch "The Matrix" or, Bruce Willis movies such as "Last man Standing" and all that.
Or movies such as Troy etc." or any of the comic-hero movies these days.

Not that I wouldn't love to see more of a struggle like during the duel but in terms of powerlevel, it should be seen as "professional boxer vs some random street thugs".

I don't like the "powerjumps" though
