Here's a representative quote: "I am deeply sorry to be severely disappointed by the styling of the C8. I hoped for something really new and exciting, not a boringly generic supercar, mostly indistinguishable from the many and varied unimaginative devices that show up regularly at the Geneva auto show."
The stuff beyond this, I somewhat agree. I like some of the lines on the C8, but some of the stuff on both the front grille surfaces and the rear end seem busier than they need to be.
However, I would never expect a mid-engine Vette to look anything other than like a "boringly generic" mid-engine supercar. All the lines of a "generic boring" mid-engine supercar are driven by the human form, geometry, physics, and aerodynamics.
We're a long way beyond car designers being able to design nearly anything about a car beyond trim work. Back in the 1960's, you could make a car look unique. We had wind tunnels but we didn't have advanced computer design methods. We didn't even really understand downforce much--there are reports of some sports cars having tendency to "lift" at high speed instead.
Now, cars are designed in computers and wind tunnels to achieve drag numbers [and for sports cars, downforce numbers], and basic geometry and aerodynamics give you very little wiggle room. So cars all look identical except for the trim.
So some cars try to stand out with angular lines [Corvette, recent Acura designs]. Some are more clean, flowing designs [Ferrari, MacLaren]. Others try to stand out with distinctive styling cues [the gaping maw of a front grill that you guys all hate on the Lexus, but oddly I really like].
But all sedans look basically the same. Same shape. All crossovers look basically the same. Same shape. And all mid-engine supercars look basically the same. Same shape. Because they're all being designed based on the same constraints of the human form, geometry, physics, and aerodynamics.
