It misses a certain chemistry to it and the whole base of operations cast and set is just all flash and no substance and Michael and KITT just don't have quite the same chemistry as the original.
I think Michael and KI3T are beginning to show that chemistry, especially in "Journey into the end of Knight". However, I will say that in TOS Michael and KI2T established that chemistry
much faster. I am also of the opinion that the cast is far too bloated. Torres is fine since it seems they're setting him up for some type of fall, but Zoe and Billy could disappear without taking too much away from the show (and I'm saying this even though I enjoy the characters).
