Other than maybe C5, people have said that about every generation of Corvette, yet we later look back on those same models nostalgically. Heck, I’d bet folks complained about C2, when it was released.
Others complain about every new iPhone, until they have to go back and use an old one several years after adjusting to the new. The C7 and C8 will likely grow on you, with time, people just dislike change.
IMO, the worst era for Corvette was C4. I always liked the C3’s best, which everyone else was trash-talking until just the last few years. For some reason, the C2’s always get the most love, but I would rather own a C3 Stingray with a roots-blown smallblock. If not turn down a C6, either.
