Star Trek really drove itself into the fround with Nemesis and Enterprise. With the cancellation of Enterprise we saw a world without a current running ST TV series for the first time since the long gap between TOS and TNG. Nemesis, though set up with an ending that demanded a sequel, always had an air of being the last one to it, even in its advertising. After Nemesis, we all knew it would be a very long time before we saw another ST in the cinema. After Enterprise, we knew there would very likely never be another ST tv series again.

Nemesis was not set up with an ending that demanded a sequel and it was clear that it was the last TNG-era movie. The next movie planned was going to be about The Romulans Wars set around the time of ST: Enterprise.

Star Trek: Enterprise was bad in the 2nd and 3rd seasons, but the four season was started to turn it around (just like most star trek shows). The fact is that Star Trek: Enterprise did just as well as past TNG-era show like DS9 and VOY.

What really caused the cancellation of Enterprise was CBS buying out Paramount.

The United Paramount Network (UPN) started with Star Trek (UPN's The first telecast, the two-hour pilot of Star Trek: Voyager).

Once CBS was set to take over of Paramount, Star Trek: Enterprise was canceled and Paramount Television released all The four seasons of Enterprise which seemed fast (all The four seasons released in one year). also The Romulans Wars movie plans were canceled. allot of people who worked on Star Trek for the past 18 years were fired.

after 18 years of non-stop run Star Trek was dead.

After CBS took over Paramount, they started on new projects like Indy 4 and a new star trek movie with a "younger cast".

CBS-Paramount hired J. J. Abrams (oddly on the same day, the shill web site: trekmovie.com started).

then CBS-Paramount fired all the people who worked on startrek.com just two weeks before chrismas.

It really seems like the Viacom owned Paramount ended and killed star trek before CBS took over which has made CBS-Paramount had to made "The New Coke of Star Trek" called J. J. Abrams' Star Trek.
