I really liked these, and it's a shame they took them off the menu (I'm pretty sure they did, haven't been there in a while though). I don't think the backlash over them was fair at all, in fact I would consider it counter productive since they really were apparently lower in fat. To a lesser extent I will say that Burger King simply did not market them properly. According to their web site and official statements, all they did was lighten the coating on the fries to make them absorb less oil during the cooking process, as well as making the fries thicker which meant less surface area being exposed to the oil and soaking it in.
Admittedly when I first heard of these I thought they were either going to be baked fries or fries cooked in some oil substitute like Olestra - in reality they were neither. They basically tasted identical to their existing fries, but were just thicker and a little lower in fat. I would have liked to see these become their regular fries, to be honest.
