I feel watching Season 1 - including WNMHGB, is VERY important. Since they had SO many post production problems that first year, a prime character show like The Corbomite Maneuver got buried deep in the season. CM is very definitely a 'third pilot', seeing how its the first show with McCoy, Rand, Uhura, and Sulu as helmsman. Since WNMHGB was a prototypical pilot with styles and other things never seen again, CM is essential to view first, as it establishes just about everything we know and love about Trek. And then going through that 1st year in production, you see how each actor massaged their characters, and how the production got more and more assured. In season 2, the production process became much more settled, so they could do things like make sure Amok Time was the season opener, Catspaw could air around Halloween, and so on. The production does not matter as much as it did in the first season, as far as introducing ones self to it is concerned. Have fun!
