Ok, now that I have some time, I am going to give my opinions of the seasons
Season 1
In my opinion, an overall very strong start for Voyager.
For me, the distinguishing factor for this season is the dialogue and the interaction between the characters. All the characters here feel very organic, real and their relationships have a depth and truth to them that wasn't really seen in the early seasons of any other Trek show. Even episodes with poor plots such as Parallax and The Cloud were often saved by the characters.
Best of Trek: "Phage", "Jetrel", "Faces", "Prime Factors"
Lowpoint: "Cathexis", the kind of filler crap often seen in early seasons.
Season 2
Season 2 is an interesting combination of an attempt at a long term story arc (The Kazon) and completely episodic storytelling - the epitome of which must be "Deadlock" which was the first ocassion where it became extremely apparent the writers weren't particularly interested in having the show become completely fluid with the events of preceding episodes affecting later episodes. To see the ship nearly damaged beyond repair in "Deadlock" and then squeaky clean in the next episode was a real
moment for me.
The Kazon episodes have grown on me and I can appreciate the general story going on, but unfortunately the Kazon were a fairly laughable villain and too many holes began appearing such as how exactly a technologically behind species could even keep up with Voyager.
Overall for me, Season 2 is a very mixed big probably leaning towards more bad than good. There was an inexcusably large number of poor episodes overall compared to a much stronger season 1.
Best of Trek: "Deadlock", "Tuvix", "The Thaw"
Lowpoint: "Tatoo", misguided
Season 3
With this season, out went attempts at any types of story arc and in went endless episodic shows and an abandonment of continuity. The results were extremely mixed and it wasn't uncommon to have an atrocious episode followed by a superb episode. This led to the feeling of a lack of direction in the show.
The lowpoint of season 3 came right before the highpoint at the end of the season when we were given a stream of extremely strong episodes beginning with "Before and After" that seemed to signal the writers might have been pulling their shit together.
Best of Trek: "Before and After", "Distant Origin", "Scorpion Part I"
Lowpoint: "Favorite Son", the type of unbelievably bad filler episode that may have been avoided if we had had an arc.
Season 4
Season 4 was an immense improvement in consistency and writing quality but many people seem to forget that we were already seeing big improvements in quality towards the end of season 3.
For me, Seven of Nine was a complete boon to the show at this point. Her character was fresh and interesting, introducing some much needed tension into the mix and I found myself excited every time a new episode would focus on her - which was often!
The writers migrated once again to adding some sense of continuity into their writing as we got small story arcs involving the Hirogen and communicating with Starfleet that made the show feel much more kinetic than it had in season 3.
Some of this good energy began to dissipate by the end of the season with weak offerings such as "Demon", "Vis a Vis" and "Unforgettable".
Overall this season was marked by two feelings for me. One was the excitement of the new character Seven and the satisfaction she gave me as a Trek viewer in her storylines and the new opportunities she created for storytelling.
Another was one of loss. While season 4 was very strong, the tone of the show changed and it seemed to become darker and slightly less vibrant than it previously had been. One big reason for this was the loss of Kes who was not only a good character with a ton of potential but also seemed to have added significantly to the tone Voyager had set in its first 3 years.
Best of Trek: "The Gift", "Year of Hell", "Message in a Bottle", "Prey", "Retrospect"
Lowpoint: "Demon", its fitting that an episode dealing with low supplies, a premise that should have been central to Voyager's premise, is so shoddily handled.
Season 5
This season was when Braga took over the reins of Voyager and also when the show began to stagnate albeit at a pretty high level of writing.
While this season had plenty of great episodes and Seven continued to fascinate, although slightly less than in season 4, there was little feeling of progression or moving forward.
Now that the initial excitement of a new character had rubbed off a bit, I began to miss the Voyager of season 1 when there was fairly even attention paid to each character and there was a feeling of being lost and a bit more *emotion* to the show.
What we got in Season 5 was a very disjointed series of episodes - many of which had great writing, but little sense of continuity or cohesion for me.
I often name "Dark Frontier" when expressing my frustrations with the lack of continuity or sense of reality felt in Voyager. Janeway remarks at the beginning that they have added at least 2000 lightyears onto their journey trying to avoid the Borg, but this is something we never heard and in fact they hadn't run into the Borg in ages. It was at the point I just had to accept to enjoy each episode as it came and accept Voyager for what it was, a collection of episodes with minimal continuity between them.
Overall the enjoyment of season 5, much like the show, really leans of whether you can accept Voyager's failings and just learn to enjoy it as an episodic show.
Best of Trek: "Once Upon a Time", "Latent Image", "Dark Froniter", "Someone to Watch Over Me", "Equinox"
Lowpoint: "In The Flesh", its suitable that as we cruise into the final seasons which are mostly devoid of any interesting alien villains that the writers should castrate one of Voyager's best villains.
Season 6
This was "Voyager" on autopilot. The usual mix of excellent, good and poor episodes were churned out with very little direction.
Season 6 is notable for probably having one of the strongest starts of any Trek season however, with 4 fantastic episodes.
Best of Trek: "Barge of the Dead", "Pathfinder", "Blink of an Eye", "Child's Play", "Muse".
Lowpoint: "Fury", unbelievably badly conceived episode which was not only terrible in itself but actually managed to change events in the first 3 seasons.
Season 7
Voyager continued on autopilot and while good episodes continued to be produced, there was a chronic feeling of "more of the same".
There wasn't no development however. Voyager at this point, much like TNG, felt very "comfortable". We knew the characters and we firmly knew what kind of things to expect- some people like that.
Best of Trek: "Critical Care", "Lineage", "Author Author".
Lowpoint: "Endgame", not as bad as Enterprise's finale but still a rather lazy effort.
Overall, I like Voyager a lot. I no longer find myself getting worked up over what could have been, I simply enjoy the multitude of sci-fi concepts and stories they explored.
