Re: STVI without the racism
I always thought a great TOS episode would have been one where a full-blood Vulcan served aboard the Enterprise temporarily, and Bones got along with him swimingly, probably more so than Spock would.
Believe it or not, this exact idea was discussed for the Xon character in the Phase II
series, only on a more permanent basis.
