That's a failure of the fandom, not the show.
For what it was and what it did, Voyager was significantly more successful than it gets credit for and deserves far more credit than it gets, even and especially from some of the Trek fans who claim to enjoy it*.
* I'm including myself in this group because there was a point in my life and in my personal Trek fandom where I claimed to like Voyager*, but simultaneously couldn't accept it as it was.
I have to disagree with your statement about the fandom. As I see it, it's not a failure of the fandom but evidence of the strength of the fandom as thinking beings.
Star Trek fans are thinking fans. What they want most of all are good and believable stories in the context of adventures and space exploring, good, likeable and interesting characters, interesting villains and a good scenario with a good plot, premise and good background story for the show.
I can also add good explanations for certain events which takes place in the show and continuity in the storytelling.
OK, there are fans out there who accept only action and glosswork but that's not the majority of the Star Trek fans.
The thing about Star Trek is that, due to the the nature of the medium, changing premises is easy enough to do.
Tried of having to ration out 38 torpedoes? Trade for a hundred more photonic implosion warheads with a friendly alien race. Maybe Voyager has some bits of a Borg cube, or was able to mine some valuable ore.
Want to blow up another couple shuttles? Do what
@Lynx suggests and start a shuttle construction team.
Got a Borg baby onboard but don't want to go any further with that? Have Janeway say that the child's homeworld was only a couple light years away, and she's back with her own people.
Just invent a reasonable explanation, and we'll be satisfied.
Which is exactly what I stated in my reply to
DigificWriter above. Most of he Star Trek fans wants plausible and realistic explanations to what is going on, not just quick fixes with unrealistic explanations or no explanations at all.
I don't know what went wrong with the job Berman and his staff were doing when it comes to Voyager, especially if we consider the success of TNG where those people actually did a good job. maybe they were burned out after seven years of TNG and simply couldn't live up to the expectations of a series about a crew lost in space.
The biggets failures they did when it comes to Voyager was how hey handled things that didn't work, like the constant waste of shuttles and torpedoes, the Ocampa lifespan, how the food problem ceased to exist in season 4, the break-up between Kes and Neelix, the purpose of Harry Kim, the ship being shot almost to pieces and then totally restored in the next episode and some otherthings as well.
When something didn't work, they just ignored it and kept going like if the flaw never existed, like "ah don't bother, the viewers won't notice". But the viewers did notice!
And when there was another Star Trek series running at the same time where each and every strange event and even flaw was explained in the most realistic way available, no wonder that people started to compare what was going on in the both series, a comparision not to Voyager's advantage.
If you are a writer, then you have to know where the limits are when it comes to storytelling. If it is expected that the ship only have two shuttles and 39 torpedoes
and those can't be replaced, then the writer have to adjust to that by either don't waste any shuttles and torpedoes and if wasting shuttles and a lot of torpedoes is necessary for a good story, then the writer must come up with a solution for that, like my little suggestion about the Shuttle and Torpedo Building team or so.
The same with the ship being almost shot to pieces in an episode like
Deadlock and then look as good as new in the next episode, well either don't write such a scenario or let the ship look damaged for the next 4-5 episodes with some explanations thrown in about how they will manage to fix the problems.
I must admit that the DS9 writers had it easier there. They could at least bring in some Starfleet ships and personel to assist the station crew to rebuild damage parts of the station and order a bunch of shuttles and torpedoes to be brought in. But if Voyager is supposed to have limited resources, then they must stay with that premise and the limitations with it when it comes to writing. Or come up with a plausible scenario which is explained to the viewers.
The worst failure with the writers were that they couldn't handle what they had. I mean, they had a bunch of great and interesting characters but failed to develope and use most of them in the same way as the DS9 writers managed to do with their materiel.
Let's take my "favorite subject" Kes here. Some of those who dislike her claims that she was boring and bland. I must state that I disagree here.
But I admit that Kes could have been written much better. She had the potential to out-do Deanna Troi in most aspects (no offense to Troi who I actually like but Kes had more potential). Her mental abilities combined with her wit, courage and curiosity could have been used in a lot of ways which would have made the character even more interesting but it never happened. When she was dumped, the writers claimed "that they couldn't come up with good stories for the character" which was not true since they actually did come up with some good stories in the first three seasons. If there were any truth in the statement about "not being able to come up with good stories about her", then it was because the writers didn't even try. I mean, they couldn't even come up with a good and acceptable break-up story between her and Neelix. They realized that the relation didn't work but just let it float for almost one and a half season before they came up with that weird break-up in
Warlord.
And it wasn't only Kes. In fact, Harry Kim suffered even more when it comes to bad writing, or more correctly lack of writing. Kes did at least have a couple of good episodes and scenarios during the years. Kim had
Non Sequitur and
Favorite Son.
Then look at the Voyager novels where Kim is actually doing something! OK, the scenario with Kim being badly injured and close to death occurs too many tmes in the book, as if his role as the "whipping boy" of the show is so clearly established that it can't be changed. But he's still a lot more interesting and useful in many of the books.
When seven arrived and more and less took over the show, Charaters like Chakotay, Paris, Torres, Tuvok and Neelix were shoved in the background too. They became as important as some of the DS9 background characters. In fact, even Nog, Rom and Leeta had more piece of the action than they had.
Some fans have stated that three main characters were enough for the show but I really had to disagree. Once again I have to look at DS) which had 10 main characters and lot of adventures and action for all of them. Not to mention excellent recurring characters like Garak, Nog, Dukat, Winn, Weyoun, Vic Fontaine, Rom and many others and no problem when it came to creating good scenarios and episodes with those characters.
Voyager's greatest flaw were the writers. With better writers, the show would have become a masterpiece. Now it became a good series with a lot of potential which was never really fulfilled.
