The laziness of there being so many duplicate constructicons and blackout/bonecrusher just... showing up. Thats not even touching on all the decepticons that just stay in their protoforms during the desert battle. Say what you want about them just being bots that look the same, or the precedent set by the G1 seekers and prowl/smokescreen/silverstreak, but at least they were all different colors. Look at Mixmaster, we see guys like him all over the place. There got to be at least 3 bots in the movie who look like him, as there are two in the desert, and I can't see how the one in New York would have gotten to Jordan. Furthermore, for all we know, there could be like 4 different bots who all look exactly like Longhaul: The one we see in the ocean, the one who makes devastators leg, the one who just pulled up randomly to the excavation site, and the one fighting amongst the buildings. That seems extreme, but what do the film makers give us to make us think otherwise? All the clones, coupled with the high proclivity for wheel-feet bots (though i do love Sideswipes design), just made me a little disappointed in the design staff for this movie, and took me out of the film more than any other aspect.
