Farscape is similarly a show about one ship on its own with no help, but rarely ever did a "the ship is damaged and stays damaged" story. Only once or so in the show's entire run did they do that and it was only for 2 episodes. It also gets no external support but no one whines about it as much as VOY.
All shows had recurring alien enemies who kept showing up despite either not knowing where Earth was (Stargate) or the protagonists always being on the move (Farscape). But when VOY did the same thing all it got were complaints that bad guys shouldn't keep showing up.
VOY gets complaints over how the ship is having too big an impact on galactic events, but Farscape and Stargate do the same thing having a huge impact on their Universes and no one cares.
I'm sure there's more, but the matter is that VOY suffers from double standard and too many no-win scenarios with the audience.
EDIT: Then there's the Borg criticism as well, that was another no-win scenario/double standard thing with VOY: Despite TNG showing it was possible to even DAMAGE a Borg ship, VOY's audience couldn't handle it happening and felt that the second a Borg ship was shown with any damage to it whatsoever the Borg were utterly ruined to them.
I guess a lot of that wasn't stuff I gave Voyager flack for. I gave it flack for having uninteresting characters, bad writing,
boring aliens of the week, and ignoring it's premise entirely.
See, the promised premise of Voyager was that they were stuck in an area of space where they didn't know anyone and would have to struggle to survive and, oh yeah, they had to take on the Maquis survivors who hate Starfleet. That was a great setup. They never lived up to ANY of that. The Maquis was pretty much integrated after 3 episodes and it's not interesting to watch a ship trying to survive when really, there's no indication that they're having a hard time of it other than the occasional episode that tells me they're having a hard time of it (which again, is just bad writing). If you're going to start with that premise, be prepared to show some damage to the ship, some hodgepodge uniforms, don't be afraid to slowly wreck your sets over the seasons... All of this would have made for a much more compelling show. Also, if they had to ACTUALLY make a tough decision now and again that affected them, that would have been much better too.
Also, it would have helped if they hadn't written the characters by committee. Just a boring bunch of folks.
