For me, Voyager ended when Kes was dumped.
And not only that! My interest in Star Trek took a heavy blow too.
Up to that, I had been a 100% fan. I watched TNG with great pleasure and also the few episodes of DS9 one of my pathetic channels did air (only first season) and my interest started to go on overdrive when Voyager arrived.
Up to then, I couldn't understand the criticizm of Berman, Braga and the others in charge which from time to time turned up on various forums. "Why are they complaining? They have given us a great show!" I thought.
But when Kes was dumped and the aftermath of that gave me another view of all that. It was so rude, so unnecessary. "They are trying to show us a better future and then they act like greedy, sex-obsessed Ferengi" I thought.
As a protest I stopped watching Voyager there and then. After all, I did have TOS, TNG and the first three seasons of Voyager to watch.
But I couldn't abandone Voyager. After two years, I did have an urgent need to catch up with the old favorites again. Not to mention that I had hope about a Kes come-back. After all, they did bring Dr. Crusher back, didn't they? So I borrowed tapes from a shop which rented Voyager VHS tapes to catch up with what I've missed. But I must admit that it wasn't the same as it had used to be, something important was missing!
Finally I did catch up with my local station's airing of Voyager, it was in the beginning of season 6.
Then
it happened!
The horrible insulting s**t episode in season 6!
Fortunately I was warned by some friends in the US where
that episode had been aired several months before. But I had never expected such a disgusting, insulting, humiliating piece of crap which was thrown into my face.
So I stopped watching, this time for good. The only episode I watched after that was "Endgame". I made up my mind to watch it about 60 seconds before it started on TV. Afterwards I wish that I had never watched it at all. A sad end to a series which had started so well.
Not to mention that the purpose of that episode in season 5 was to turn Kes into a horrible monster, it turned
me into a monster as well which everyone who did encounter me on different forums must have noticed.
All of that was a reason why I couldn't stand "Enterprise". OK, I had been against a retro series even before "Enterprise" started and when it started I was put of by the boring characters and the constant screw-ups of established Trek history. But worst of all was seeing Berman's, Braga's and Fuller's names on the credits.
I guess that I'm more civilized now when I'm trying to see all the good things with Star Trek. After all, I do have my TOS, TNG and DS9 dvd's and most valuable of them all, the three first seasons of Voyager!
