I dislike and completely disregard TOS... ...I mean, sorry, but it's just... ...cheap! It was a flop! Cancelled after only 3 seasons, it did worse than ENT. It only gained all the hype through the movies. TOS isn't really Trek, its far too non-idealistic (especially with chauvinistic, aggressive Captain Rambo Tiberius Kirk) and has as much science and logic in it as George W. Bush's brain.
"TOS isn't really Trek." Uh... yeah. Right. What, were you born in the 1990's? TOS is the beginning of it all. If it never was, all that followed wouldn't exist. So, to say it isn't really Trek is just... well, completely without merit.
Flop? No. It was one of the most expensive television series of its time. The ratings system was in its infancy. And the Star Trek executive producers had to constantly convince NBC that it was what the public wanted. There were enough Westerns (but NBC wanted more). A good sci-fi series needed to be there. Gene had to call it "wagon train to the stars" in order to get it through the NBC executive board. But by the 3rd season NBC decided to move Star Trek to the "death slot", late evening on Friday. And that effectively killed it. If it really was due to the series being junk, there wouldn't have been such serious success in syndication.
Yes, you got that right. There was no hype needed for the movies. Star Trek was very popular in syndication, enough to spawn the first movie in 1979. That was 10 years after TOS had been canceled. TOS was ahead of its time and finally recognized after NBC pulled it. There would have been a "phase II" series, but... various complications ensued. It eventually became TMP movie.
So before you stand up and bash TOS, you might want to get your facts straight.
There are so many scientific liberties taken in Star Trek series and movies. TNG tried to sound too legitimate by choking the dialog with techno-babble. It was really too much. It was also too idealistic, making characters look too perfect and sterile. It also created a number of conflicting ideals, like there being no concept of "money" in the Federation. Hah. Anyway, TOS could have benefited with a little more techno-jargon, but overall it was fine. And yeah, the special effects look very dated today... but that has been taken care of with the remastering.
So I wouldn't completely disregard TOS. You have to watch it with respect of when it was made. The cultural influences of the 1960's. It's classic sci-fi. And it's filled with many treasures worth seeing.
