The Omega Glory (TOS)...good episode until the silliness of the American flag/Constitution just kills it.
"The Naked Time" this morning. Nice use of entire ensemble, I note this time around. Even with two showy guest-turns by Tormleon (sp?) and Riley, and big emotional breakdowns for both Kirk and Spock, all the regulars get some attention. Uhura and Yeoman Rand even get to take the helm at various points!
Is There in Truth No Beauty? (TOS). I never understood how a box full of colored lights could be ugly enough to drive humanoids mad.
