Trolled? The only people trolled are the uncreative studios churning out the same shit year after year that came before Haruhi, fucking with the same tired formula and spewing it out for everyone to eat up. Haruhi completely and utterly destroyed that and has had the anime industry on its head trying to figure out just what Haruhi did and has been trying to reemulate it, but is failing miserably. The beautiful part? Haruhi beat the formula not by challenging it, but by actually using it. It took the tired high school anime with retarded supernatural elements and perfected it, and then turned right around and subversively mocked the entire industry through that perfection.
But to tl;dr - every other studio in the world trolled, but the audience was given pure genius.
