Just watched this series via Netflix streaming.
I liked, except for this:
I never got into SGU. I watched and rewatched the first two series. SGU was just too slow, I was always wanting to yell at them to get the hell on with it.
No kidding, it was slow.
They NEVER resolved what was going on with the blue aliens, and they jumped the shark when they introduced the drones and the meaningless side-detour that got them involved with the drones in the first place.
Remember the "intro" to the show where they would re-hash everything in the hopes of bringing a new viewer up to speed so they can understand the episode? It never changed, and it kept talking about the blue aliens, a lucian alliance plot against earth, and some other stuff that never got resolved.
Destiny's mission to find out more about this background radio signal was neat, but it was a million+ year old mission that still wasn't completed. It was utter hubris for the humans to think that they could have ANY affect on that mission at all... even within our species' combined lifespan, let alone the 80-odd year individual lifespan. Their idea of being relevant at all to Destiny's mission was laughable. The fact that they detoured the ship to investigate something completely unrelated to Destiny's mission was unconscionable.
They should have all transferred over to the seed ship they docked with and used it to locate another Icarus planet, then built a 9-chevron gate to travel back to Earth. It would have been a graceful way to end the series, or leave it open (since they figured out how to safely build a 9-chevron gate and operate it without blowing up an Icarus planet) for future series.
Yeah, it's fiction, but... I'm disappointed that the only thing that humans contributed to on Destiny's mission once able to modify the ship's flight plan, was to get it half blown up and sabotage its capability to refuel or resupply itself.
