I'm disappointed. KITT looked fine as a Mustang... that's the nicest thing I have to say about the show. The actors aren't that great, the writing sucked, and where were the super-cool stunts? The only things KITT had going for it were his AI (which got hacked) and the self-healing/color shifting exterior. That exterior thing was okay, but it's almost expected they'd have to improve on the "molecularly-bonded shell" of the original KITT.
But... where were the jumps? Where were the super driving stunts? I expected to be blown away by the new KITT's abilities, but he really doesn't have any.
Oh, and if you're going to hire a voice actor to play a car, better find one with some personality, or at least a British accent.
