Straighten all the curves - Tradução em português

"Some translators argue that it's good [that] bestsellers are translated into Finnish, even if time pressure means the level of the Finnish isn't top-quality," she said. But "there's a derogatory nickname in Finnish for translations that 'straighten all the curves', convey the storyline but skim past finer bits and nuances. Perhaps that wouldn't so diminish Rowling's new book? Who can say, since no one's seen it."
