Nitpicking specific imperfections does not translate to damning the entire practice in general. Obviously when people try something, they won't always succeed. But that doesn't mean it's wrong for anyone to try it at all. Any human creation is imperfect. That's a given. There were plenty of imperfections in TOS, and there were plenty of imperfections in TOS-R. Sometimes TOS-R improved on the original, sometimes it didn't. That's the nature of human effort. Any creation is imperfect, and that's why creators generally aren't as opposed to revising or updating their works as fans tend to be -- because nobody sees the imperfections more clearly than the creators themselves.
