Voyager was set up for internal and external conflict on a ship that was supposed to slowly fall apart as they tried to get home. A vocal portion of Trek fandom just wanted another TNG-style show and we got a tame hybrid. Limited conflict, everybody complying to the greater good that is Starfleet and an unlimited supply of shuttles (later replaced by an indestructible one) Voyager existed in a near permanent status-quo for most of the show, except for a few token episodes where Voyager was supposed to go through a bad patch, but there were no real permanent scars.
I agree wholeheartedly, Voyager was all about status quo and, in my opinion, a wasted opportunity. They really could have done a lot more to explore the differences in the Delta Quadrant and the consequences of being stuck hundreds or thousands of light years from home with no support. Instead we get a warmed over rehash of TNG with just a bit of set dressing mostly to differentiate the Delta Quadrant from the Alpha & Beta Quadrants. Being in a completely different part of space with no prior contact with any Starfleet, Klingon, Vulcan, Romulan, or any other familiar tech it's rather amazing how compatible Delta Quadrant tech is with the Voyager and rather convenient that their hailing frequencies were the exact same, and that the universal translator worked perfectly with species that developed completely separately from their part of the galaxy.
The producers really needed to push the whole lost and far from home angle a lot more. They should have had a lot harder time finding parts and they should have at least mentioned if not shown them doing more jerry rigging to get things to work and especially working with each other. You shouldn't be able to pull parts from, say, a Klingon Bird of Prey and stick it in a Galaxy class starship and expect it to actually work and this is with a culture that's had long and regular contact with the Federation; hell, it would be asking a lot to expect, say, a warp coil from a Sovreign class ship to fit and work on an Intrepid. There's issues of size, shape, connections, power output, power limits, and a whole range of other issues that would keep you from pulling parts from one type of ship and sticking it in another, that's why you can't take parts from a Toyota and stick it inside a Honda, it just won't work.
The other thing that they should have done was to make the show more serial instead of episodic, build on everything that happened in previous episodes more. Show the Voyager getting more and more beat up looking, more run down, systems not working or not working at optimal levels. because there's no way that a starship stuck thousands of light years from home without access to a Starbase for spare parts, regular maintenance, and not to mention repairs, could stay in such good shape.
Lastly, has anyone ever done a calculation of all of what I call "free rides" where they get these big boosts that cut hundreds or more light years off of their trip the Voyager got? I've always suspected that the writers never kept track of the free rides and it wouldn't surprise me if we added them up and found that the Voyager should have been a lot closer to home than they said they were or even all the way home well before the end of the show.
