Unfortunately, that consistency means if the pdf is somehow suboptimal for a particular device, it's harder to get optimal output.
For the most part, pdfs are formatted for printing on standard paper sizes. There's no reason they have to be formatted that way. One can just as easily generate Apple Ipad mini-sized pdfs. For example, i've been reading a Japanese pdfs formatted for the Sony Reader. These look pretty nice. (PDF is also the only way to get vertical Japanese text on my reader.)
And therein lies the problem, most PDFs are formatted for A4 or Letter, and being non-reflowable format, PDFs don't display well on 6" (and though OK, not great on 10" either), and hence make for a poor reading experience. The "bashing" you refer too is not for the format per-se, but how it renders on small screen readers.
