Vanguard is the series that finally made me interested in the TOS Era.
I've always had an odd understanding of TOS. I've seen all of the movies but not all of the TV episodes.
Mostly, I just liked the movie versions of the characters better because they seemed more realistic than those of the world portrayed in the TV series.
however changed my mind completely. I get it now. I get why people like/liked the TOS Era. (The S.C.E. guys of the USS Lovell
helped out too!)
It has become my favorite ongoing Trek Series now that the DS9R has slowed down & Klingon Empire
has fallen off the map. (So Sad.)
