First of all: Star Trek is more than I have ever imagined it could be, but at the same time, as a TV show, it's worse than I've hoped it would be.
I'm not an easy guy to get moved by something, especially now that I have more or less gotten out of puberty and am able to laugh to fart jokes again. But Star Trek managed to get me thinking on so many subjects, and tackled so many difficult issues, often ahead of its time - including addiction to videogames, that it has resolved with 'everything is fine in healthy amounts' as opposed to 'getting lost in fantasy is evil', which is just amazing. And... It goes like this with everything, really - I was expecting it to pull the traditional Christian morality at us and 'enlightening' other races in the fictional galaxy with it. Instead, Star Trek preaches to embrace even cultures that would, to us, seem foul and evil. And that is fantastic. I could just go on, it's full of opinions and resolutions that are reasonable and make sense outside of boundaries of what would normally be 'proper' - I guess that's how it has gotten its fame too.
On the other hand, with all it does right, I just can't but feel that as TV series it also does a lot wrong. Star Trek was utterly unable to get pacing of its episodes right 'till about half way trough the Voyager, and while most episodes had an interesting main plot, there usually were sub-plots which raged from sub-par to rightdown silly. A lot of weird filler episodes didn't really help either. I feel that as a best TV show, Enterprise wins hands down, especially when it gets its continuous story arc going. As for my favorite Star Trek series, as far as I'm concerned, Voyager wins - it seems to combine what I liked about The Next Generation with what I have liked about Enterprise, and mix all that with a stranded theme that I simply love. Then there's the oddball of Deep Space Nine, that I... Kind of liked, but Babylon 5 just wins on all fronts there.
Now, to the second thing I wanted to talk about a bit: The Star Trek reboot. I have actually seen it before I have started watching ST, and I had absolutely no idea why would somebody hate it. And... Now I finally understand. I don't know if today's average viewer is just not interested in anything at least a bit more deep, but what I can see is that this reboot has effectively erased all that has happened in the other ST shows, along with a hope that we could see continuation to Star Trek actually dealing with difficult issues in a reasonable and humane way. And that's an incredible shame.
Well... Sorry for the wall of text, just wanted to put that out there. I'm not even going to proofread it, I hope someone can make sense of my ramblings.
