^ I think even the producers of the show have admitted they would have prefered a more serialised style, but were explicitly stopped from doing that by the network (UPN).
Then they should have adopted a premise which would have leant itself more towards an episodic approach ala TOS and TNG. Seialsied doesn't always mean better than episodic and vice versa, just that you use the one which best suits the overall premise of your show. Which a fair few believe VOY failed to do. The fact that the edict might have come from the network is irrelevant, one of the key critisims levelled at VOY was that it failed to live upto it's premise. Would it have been a better show if it was more serialised no one can say. I suspect that we would be having a similar debate had it been for those that favour a more episodic appraoch to their TV.
It's the simple fact that you can't please everyone all of the time, some people love VOY for what it was, others feel they missed an opportunity and the biggest sense I get is that a many were disappointed in what we got. Not hatred but disappointment.
The thing is, and I've seen it argued elsewhere, TNG didn't have this reset-button mentality. Sure, it wasn't overtly praying at the altar of serialisation, but they did have this "unspoken agreement" that episodes could be left with threads hanging, and that later episodes could pick up those threads and run with them. Out of that we got the Duras storyline, we got Worf and Alexander, we got the ongoing thing with Data/Lore/Soong, we got Romulan episodes that built upon each other, we got Hugh Borg... on the whole, TNG had an open universe, where decisions in one episode could (and often *did*) come back and bite them on the ass in a later one. While that wasn't exactly serialisation, it was hardly the reset-button either. And TNG did explore many ongoing arc plots as a result. It's a part of what made the show really come into it's own.
Voyager's conceptual problem, more than anything else, was that the crew have got a fix on their location in the DQ, relative to their start point in the AQ, from the very beginning. And a constant mission to "set a course... for home". Which naturally meant that by it's very nature they would constantly be leaving things behind that would never be picked up again. If Voyager had been truely lost, and had to "fly blind" in their adventures in the Delta Quadrant, then there would have been more opportunity for them to be going around in circles and picking up ongoing plots involving semi-recurring characters. Just like TNG often did.
Voyager didn't need to change. It needed an open-ended format to begin with, but it didn't get one, it got the USS Reset-Button instead.
Sure they are moving on from one adventure to another, but what about things that don't rely on that such as the crew, sure some characters such as the EMH had growth but others had very little character growth. What about secondary characters, lets look at O'Brien from his TNG days we got to know him as a character over the 55 or so episodes that he appeared in. Sure VOY had the odd secondary character who appeared in a few episodes then was never brought back, almost as if the writers thought they had killed them off.
Besides there is still plenty of scope for introducing arc story lines even given VOY location. They hear rumours of a race who might be able to help, or a race has heard they plight and comes looking for them, wiull they help or not?
