SciFi in general:
I hate parallel universes.
I hate time travel.
Disco specific:
I hate the Michael is Spock’s sister idiocy.
I hate the psychoanalysis not just in every episode but in every action sequence as pointed out above.
I hope Space Bonnie and Clyde.
Every time someone says “the next clue” a writer should have their pay rescinded.
Per your first section:
This is a major part of the problem with post-Endgame MCU: it’s stepping into the sci-fi section that most people can’t stand.
I’m ok with time travel if it’s done right. And by “right”, I don’t mean that it has to be somewhat scientifically accurate (like Interstellar), but that it’s not just a cheap/lazy ploy. Without time travel in movies, we don’t have The Terminator, T2 or the Back to the Future trilogy.
I was disappointed when I heard that Endgame was going to be resolved by time travel. In the end, I enjoyed where they went with it; revisiting the previous movies was fun if a little unoriginal (BTTF 2 having done it before). Endgame was somewhat self-aware with how they handled the initial time heist, but then abandoned that to allow Captain America to show Peggy Carter his summer soldier.
Specifically for Disco, its leap forward to the 32nd century (or something like it) was necessary because they were chewing up so much of the TOS-era history that they had to get it the fuck out of there. In the end, the plot motivation to do it - to get Control out of the way - was rendered moot when Control was destroyed before they initiated the jump.
Trek has always had time travel and a parallel universe going back to TOS and the associated movies. Some of the time travel heavy movies, like The Voyage Home and First Contact, are some of most loved entries in the movie lineup. Same with mirror universe episodes in the TV series.
Sadly, like everything else they did with Disco, they misused them. They decided to use them because they could, not because they should.
But even that showed wisdom where you don’t let plot mechanics overwhelm story. Are there plot holes in Steve remaining in the past? Sure. But you’ve emotionally invested enough by then that you want Steve to have the happy ending.
Also helps to put it at the end of the story so you don’t have to deal with any narrative consequences afterward.
Literally or figuratively? Or both?
Or so that you could build a whole new movie/series out of the consequences.
I said what I said.
Re: time travel
I’ll tolerate it and even enjoy it in some shows/movies.
Same for parallel universes. Rick and Morty is great for example.
But Disco seems to be written in a round robin fashion much like the way the bridge crew came up with the solution to prop open the worm butt in this episode.
The bridge crew round robin was a thinly-veiled effort to get the audience to remember the names of the bridge crew.
I still don’t and I don’t care.
I have started a re-watch of The Expanse. Re-watch isn’t strictly true, as first time around I fucked up and somehow started watching S7 before I’d finished S3. Once I realized that, I stopped watching as I was not sure where I’d broken away.
Two good things: it’s now in 4K and looks great, and I had forgotten enough of what I’d already seen that I am getting more out of it than just a re-watch.
I am looking forward to getting into the seasons of the show I skipped and to ultimately finishing it.
A second time through on the Expanse is way better because now you have an understanding of the rules of the universe and all the factions.
I watched the first season.
It was pretty compelling, but we never started season 2.
Yeah. I was able to pick back up on that easily. First time through I remember being so fixated on trying to figure out who were the good guys and who weren’t, instead of understanding that the situation with everyone is entirely fluid.
I’m three episodes in to S2. It’s excellent.
The science is a bit jarring too because they tend to lean more toward real science so understanding this isn’t Star Wars or even Star Trek took some time.
So it’s clear to me now that I veered off somewhere early in S2. The bulk of the season is absolutely brand new to me. It’s also fantastic and the finale was 
.
Season 2 was the Leonardo DiCaprio from Django meme for me.
Chrisjen has flat out some of the best lines of any character in any show anywhere.
To wit, giving instructions to an incredulous MCRN soldier, “…or I can have Holden space you for being an intolerable idiot.” 
Amos will forever be my favorite character.
Agreed.
I don’t know if we ever find out if his empathy was burned out, but his matter-of-factness about what he does, and then his confusion as to why he’s so matter-of-fact about it, is fantastically played.
He also has some great lines.
