TOS is just a crappy show by today's standards. I mean, the 'In A Mirror, Darkly' episodes were more of a joke than a realistic bridging between timeframes. The Defiant looked so basic and corny that nobody actually believed it was this highly advanced future-ship.
I mean, the refit Enterprise looked nice, and I did like the movie versions, I hope Star Trek XI provides a good re-imagine, as it should be. I mean look at Battlestar Galactica. The old version looked crappy as well, and they completely redid everything in the new series. And isn't it a brilliant show?
