The series has so many memorable plot lines and had a superb cast that did a tremendous job on such a low budget. Re-takes were virtually non-existent so most of the bloopers were broadcast adding to the entertainment value of the series. The interplay between the actors was probably the best that I have ever seen in any television series. This series spawned two theatrical movies, a Broadway play and a revival series in 1991. Additionally, almost 29 years later conventions draw more fans than any other series ever made (except Star Trek) and having seen just about every episode I can understand why.
