Fan productions change what star trek looks like, and therefore I tend to lose the familiarity, closely followed by my interest.
Well, given enough time, actual canonical Star Trek
productions change what Star Trek
looks like, too. Fan productions don't have a corner on the market for making changes in the Star Trek
universe. After nerarly fifty years, the Star Trek
universe has changed--sometimes subtly, sometimes dramatically.
And, for that matter, after fifty years, even real
universes change, too. I'd be surprised if the Star Trek
universe exists in some kind of statis chamber--impervious to the effects of time.
