And that's what makes it bad. At least when you're paying about $100 a pop for something. Maybe "undesirable" is a better word if you wanna get picky (eyes craggy) but if you're paying that much for something you really want it to be the best representation it can be. And a big part of that look is the head. TFC tends to stray too far. FP walks a fine line (and stepped over it int he case of the Insecticons).
I definitely agree that the faces are important. The FP Insecticons are definitely off, but didn't mind too much in their case because I never had much attachment to the originals and the designs of the bodies themselves (and the weapons) are quite different. Kickback has his antenna and Bombshell, who was the only one of the three I ever seen any kind of character from in the comics, looked close enough.
Dinobots are a little more important to me, at least Grim and Swoop. So long as the other 3 are all just normal sort of faces, I'm not sure I'd notice too much difference. They were all quite generic weren't they? Well, one of them sometimes had a red face...also sometimes one of them was invisible, and not always the same one.
