..because most keep comparing every Trek to DS9?
That seems to be the conclusion of nearly every issue you read about Voy. here.
"Voyager just was as good compared to DS9 because Ds9 did it this way......"
I don't think most people who are negative about Voyager would have liked to see it try to imitate DS9
per se. The reason why DS9 is brought up is that it is an example of a Trek show that took some risks, did things differently and broke with established dogma about what a Trek show could and could not do, could or could not be about. Not everything DS9 tried worked out in the end, far from it, but there was creative energy at work on this show: the writers tried hard to make something out of all the regular cast members and many supporting characters, they tried to do some ambitious storylines and deal with some challenging ideas. They could have coasted along on "TNG-standing still" episodes and basically survived on backwash from a more popular show for much longer than they did. Instead, the writers broke the mold a bit and tried to give the show its own identity.
That is what Voyager needed to do imo. Not try to imitate TNG or DS9, but find its own identity. If that meant fighting a bit harder with the network, then fine. If that meant working within certain constraints, then fine. DS9 didn't get to do everything the writers wanted to do either. I understand that Voyager had less freedom as a network show, but not all the blame can be laid at the door of some nameless executives. Try something.
Anything. If the studio won't let you damage the ship, work on the characters. If the studio refuses to let you do any serialized storylines, make a plan for individual episodes that makes them feel like a coherent progression and gives them a sense of momentum. DS9's Season 5, often considered the show's best season, is not serialized in the traditional sense. There is a two-parter in the middle of the season. Beyond that, everything is built around individual episodes, but it feels like a coherent whole because a lot of thought was given to how the pieces fit together.
Doubtless the studio played a role in Voyager's creative struggles, but the bottomline, from my point of view, is that the show's creators were on auto-pilot. They had a formula that worked okay and simply had no interest in making the effort to do anything else, even if that meant producing a mediocre show instead of a great one.
