Oh, I disagree. Discovery used the MU far more effectively than DS9. It played very well with the tone set by TOS and ENT. It plays to human vice like TOS played to virtue.And so far, yeah, a mirror-centric season 2 would have been better than the evil AI S2 that we got.
but they gotta have fun with the mirror-verse. Ham it up some like they did on TOS, DS9 and Enterprise. They took themselves way too serious in the Disco Mirror-verse.
They could also dial back on the production design too. There’s a reason the phrase is “keep it simple stupid”. Sadly SNW and Disco ignore that far too often.
Yes, I think Season 1 focused on the Klingon War, get to know Lorca, his effectiveness in battle then explore how he wants to gain power.
Season 2, more with the mycelial network and in to the MU.
MU design is gorgeous.
