Kadh, I had someoneelse read this and they agreed with you. More succinctly, they said the were pretty pissed off that they made the emotional attachment to some of these people and their ship, and then had be blow it/them up. They didn't quite phrase it as you did, but I still think this is TOS. Most of the main characters are still alive, even though the ship and other main/supporting characters are dead, so it's kinda STIII-ish.
I both agree and disagree with Kadh.
I believe that, if you were trying to recapture a completely TOS feel, you failed. While the style is sometimes criticized as unrealistic or comic booky, Kadh's comments about how the story ends up in a 'pure Star Trek' tale are correct. I personally don't see this as a failing of Star Trek. TOS' purpose was not to be a gritty series like Battlestar Galactica (the new one) where the survival of the characters is always in doubt. It's more a morality play, taking familiar characters and placing them into a situation that presents a modern-day (or sometimes timeless) problem and seeing how heroic icons would work things out.
So your story is not TOS. I won't, however, go so far as to say it's not Star Trek.
I'm a big fan of the Star Trek universe for a variety of reasons. When I was younger, it was the cool ships. Nowadays, it's more because of it's immense size and potential for unique stories. I think that you can do all sorts of things in the STU and it's all Trek, it's just not the same Trek as everyone elses. So to me, your story is Star Trek, it's just your personal take on it. It's a story you created, set in the STU, without any intention on your part of it being The Original Series because it's SAT (Scottish Andy Trek).
Now as for the story itself...well, I enjoyed it, despite feeling the same thing that your other reviewer mentioned. Bad thing would occasionally happen to Starfleet vessels, probably when they were, in fact, trying to save the day, but it's still a letdown to read an entire story based on these people, then have the lion's share of them killed in the end. Sure, things like that happen, but the question of 'is it entertaining to read about' is open to debate.
Honestly, part of the problem may be the last two chapters. Somehow...and I'll have to reread things to try and expound on how, I'm not quite managing to verbalize it yet...the destruction of the
Lor'tana seems forced and a bit contrived. There's something in there that makes me think 'this ship is going boom for no other reason than the author wants it to'. This could be solely my own perception. I'm not sure. If anyone else felt this and can formulate why, I'd appreciate it.
The basic premise I wanted to convey here is that not everyone is as good as Scotty & Co, and sometimes bad things happen to good people. If I made you feel that way, then I can come a way satisfied.
I have a quibble with this. No, everyone in the STU isn't going to be the crew of the
Enterprise,
Hyperion, or
Hiv'laposh. On the other hand, we're still talking about Starfleet officers, who've seen and done things most average joes would never think of and who do the things they do on a day to day basis. For the most part, in this story, you captured this effectively, which might be part of why the ending seems a little contrived because I sort of lost the sense of this in the last chapters.
Overall opinion: Good story with some blemishes I have no idea how to fix, or even if they should be.
