I think mostly the people that complain about the transmission are those that have never driven a manual or ridden with a skilled manual driver for any length of time.
My MazdaSpeed lurched and bucked during low speed maneuvers in parking lots. A lot of it had to do that first gear was really nearly useless. The car didn't like being in first gear and it told me about it. Even the most skilled manual driver (even a computer) makes little mistakes here and there...I don't think people expect these little mistakes in their "automatic" car so they freak out.
