Honestly I think the biggest issues are the fact that all modern sci-fi TV series are streaming series where you only have like 10 episodes per season and, for whatever, the executives at these streaming companies basically tell them what they can and can't do because of the audience who is watching.
Or rather...the audience that isn't watching, for some reason (execs like seeing viewing numbers go up), the execs really want to make sure these shows aren't something you have to actually pay attention to to understand what's going on because a lot of people just refuse to actually sit down and watch a show and might just put it on and then be on their phone or eating dinner or whatever and only half paying attention to it.
They don't just want the hardcore fans who will sit down and pay attention, they want everyone who might just turn it on in the background too and they want to make sure that you can still understand what's going on even if you're not fully paying attention.
The low episode counts per season is also bad, especially if you're a fan of Star Trek like I am, because part of the damn fun of Star Trek is one week you get an episode that's considered an all-time classic and an absolute must-watch episode of the series and the next week is total fuckin shite, like one of the worst damned things to air on television during the decade. (Also y'know there's just no space for the lighter/filler episodes when you only have 10 episodes and not 26)
