It's a complicated question, since the show went through many changes. The original concept behind Andromeda, as developed by Robert Hewitt Wolfe with input from Zack Stentz, Ashley Edward Miller, and others, was intended to be one of the smartest, most scientifically plausible SF shows out there, and the writing in the first season and most of the second was generally quite smart and sophisticated -- but the production company gave the show a low budget and its FX and makeup departments weren't up to realizing the writers' ideas, so the execution was cheesier than the intent.
The thing is, Majel Roddenberry and the showrunners she hired aspired to do really smart, sophisticated SF, but the production company, Tribune Entertainment, aspired to make cheap action shows with lowest-common-denominator appeal. Tribune had previously dumbed down Gene Roddenberry's Earth: Final Conflict, firing its developer and bringing in successively cheaper showrunners to make the show dumber and simpler, and they did much the same to Andromeda. They fired Wolfe halfway through season 2, so the quality started to waver in the latter part of that season. Then, in season 3, they bought in a new showrunner, Bob Engels, whose work on the show was just terrible, with nonsensical plotting, dialogue that no human being would ever actually say, and an abandonment of any attempt at plausible science. But Stentz & Miller were still on staff, and they were still writing the original version of the show as best they could. So season 3 was a mix of good episodes by that duo, terrible episodes by Engels, and mediocre episodes by the other staff writers. It felt like two or three separate series alternating with each other. Stentz & Miller left after season 3, mostly, so seasons 4-5 were generally not that good.
So there is some really good, smart, sophisticated stuff in the first two seasons, and in the Stentz/Miller season 3 episodes. Yet even at its best, it was still kind of a cheesy production. It never lived up to the aspirations of its creators, because as with E:FC, Majel Roddenberry just went with the wrong production company.
