I actually liked the premise of the Ori because basically up to that point they were fighting people who claimed to be gods but were really just aliens with advanced technology, whereas with the Ori they were fighting beings that basically were gods so it was a whole lot harder to convince anyone to side with them. The biggest problem I had with it was that the show seemed to run out of money before they could properly tie everything up, a bit reminiscent of the final season of the Expanse (over which I am still very bitter, though at least it motivated me to read the books, which do satisfyingly tie everything up). In particular, in the episode
they have basically a huge dramatic victory that merited some kind of visually impressive spectacle and instead all that happened was basically that they just turned to each other and said, "Well, so I guess that means we succeeded. Yay."spoiler
where they kill all of the Ori by sending the bomb thing through the portal
