I'm not particularly fond of the KG either, but I think I've done reasonably well against it as black.
However, I'm not one to have a calculation contest with my opponent right from the opening, so that opening's not for me.
PS: an opening you should really complain about: Budapest Gambit
Trash?
I remember when the Berlin was trash.
And the Kings Indian Defense.
And the Gruenfeld.
And the Scotch.
Todays trash, is tommorows mainline.
No opening is trash @<2000 level, if it is played correctly.
