Why were you a fan of Star Trek?
Why am I a fan of Star Trek is an interesting question (though not pointed at me, I figure I'm allowed to answer)? I am a fan of Star Trek because it use to be fun to watch before the TNG gang started to believe they were self-important and changing the world. Which bled into the rest of the spin-offs and the TNG movies.
Star Trek is entertainment. I watch it to be entertained. Abrams brought much of the fun back to the franchise. Do I still wish I got way out, weird stuff like Greek gods trying to capture the Enterprise? Sure. But I also know that modern audiences may not be as appreciative of such an approach.
I started watching TOS in 1975.
