My problem with season 4 wasn’t that it was slow, but that it was uninspired and by-the-numbers. I had worked out that the DMA was a “stepping on an anthill” situation by… episode 4, maybe? 5 at the latest. So then I got to watch one of the oldest tropes in sci-fi unfold for 8 more episodes, played completely straight. Yawn.
I’d rather watch the B-plot from S01E06 of Babylon 5 to experience that particular story again. That way I’d be done in an hour.
