I didn't see the season premiere of "Star Trek: Enterprise," and it's likely (based on the ratings) that you didn't either. But I did read a review of the episode in the Seattle Times, and it sounds like I didn't miss much. What's surprising is that it seems this already weak show has taken a turn for the worse. Worse visual effects, lower budget, and a cheesy story. So much for the hopes of reviving the Star Trek franchise.
I still think the problem is simply one of variety. Once upon a time, Star Trek was the 500-pound gorilla of sci-fi entertainment. You could either watch Star Trek or Time Trax, and that was it. As a result, everything Star Trek did was bold and new, the cutting edge of scifi, and it pretty much threw a wide net. It was the only place to see new and interesting aliens, the paradoxes of time travel, and futuristic technology. Remember the stir that the nanites caused in the Next Generation, the first exploration of nanotechnology in pop culture. Now, you've got Babylon 5, Stargate SG-1, Andromeda, and a slew of other scifi shows that explore themes that Star Trek can only handle in the broadest sense. In other words, Star Trek is a victim of its own success. By making scifi mainstream, it opened the door to so much competition that it can't compete. Plus, the name Star Trek is now synonymous with nerd. I think it's time we accept the fact that we've simply outgrown Star Trek. Or at least I have.
Bonus: Check out what Jolene Blalock (T'Pol) had to say about her role in the last season and the new season...and it's not good. Darn good points, if you ask me.
