Most of the stuff they've done this season has been rather killjoyish in nature(find the remnant, enlist the aid of the warchief, attack the rack, convoy heist...), just without a warrant involved.
Yeah, but the overall goal is to fight a war, rather than to do their jobs. It used to was (as my father liked to say), if somebody made a show about people doing a job, it was about them doing that job. Now it always has to become about some huge epic struggle, and the basics tend to get lost. Don't get me wrong, I like how the show has this big unified arc and mythology -- it certainly feels far more cohesive and well thought out than
Dark Matter -- but just getting to see competent people do their job well is fun too. There's something to be said for cases of the week, for self-contained stories about diverse situations. For one thing, it lets you see the heroes actually solve problems decisively and succeed at things, whereas in ongoing arcs, things pretty much have to keep getting worse despite the heroes' best efforts.
The first season had a good balance of episodic and arc elements, and so did the second to an extent, but this season, I feel that the actual profession the show is named for has been overshadowed by the war stuff. I just miss seeing them do their job. Their actual job, as opposed to war missions that draw on their job skills.
Indeed, this season, the whole nature of the RAC has been basically exposed as a fraud. It was all a front by the Hullen to infiltrate human-settled worlds and recruit the best and brightest to be Hullenized. So that's a question worth asking: Once the war is over, what do the Killjoys do next? Their whole profession was a scam, but they were still trained to believe in its principles -- "Take no sides, take no bribes, the warrant is all." And that kind of non-partisan pseudo-peacekeeping force can still be useful after the war ends, and can perhaps help restore stability. So how do they win back the people's trust and reinvent themselves as an organization that really is what they were taught to believe it was? That could be a pretty interesting season arc in its own right. So much fiction focuses on fighting the wars, but I've always felt that wars create more problems than they solve, and the more interesting stories are about the aftermath, how society rebuilds and deals with those problems -- or fails to -- after the war is over.
