One word: Finally!

Hopefully it will be worth all the build up but unfortunately Discovery season 4 has been a season of mostly tedium for me; especially the second half. I wish I could be more excited about this episode but maybe it will have some big and interesting surprises. The last three however…didn’t.

And by “big” you mean

Spoiler for Rosetta
the size of the 10C
. I see what you did there. 😉

I can’t say the same. Yes, the Tarka / Book subplot is not a tad overwrought but they took us to some really great places with last week’s planet being the most exciting strange new world in years. I also liked the prison asteroid a lot and that bar in a holographic sea monster… And the planet of the butterfly people… You see, this is what matters to me the most: strange, out-there locations being visually realized by new means. THAT’S what gets me pumped. The plot so far has been overstrechted but still exciting enough to link all the great imagery… I’d like to see two- and three-parters next season to avoid such a dragging arc but as long as they boldly go to strange new places, anything else is secondary… at least to me…

That’s why DS9 never became my favourite show. It’s didn’t go anywhere. No cool worlds, hardly any phenomena outside the good old wormhole… DSC is already lightyears ahead of DS9 in that category and that’s my main focus… Always has been, always will be. Sorry!

Changelins? The Breen? Fire Caves, Pah-Wraiths, and the Celestial Temple (both inside and out), they gave us our first taste of what “non-linear” aliens might be like, etc. I am not saying it’s been the most out there show, but they went places and saw things in my mind. To each their own.

That all being said we have seen some awesome strange new things in Disco this year, and frankly, I think Tarka has been the standout character as well.

Totally agreed. I wish this show would take a page out of DS9’s book and tell an exciting, well-written, well-acted story every episode. This season and the one before have largely consisted of waiting for things to happen. I want to keep loving this show, but the current storyline is starting to lose me.

look – I love DS9 and have not been terribly impressed with Disco but let’s be honest. Not **every** episode of DS9 was exciting, well-written, or even well-acted.

I really wanted 10C to be the species that created V’Ger but oh well. I can’t fault them for being bold and going with an entirely new species, but this just doesn’t seem like a particularly interesting one yet. Hopefully this week’s ep will change my mind.

It has become almost a guessing game of “how will they tease and then not show us Species 10C in this episode”.

Lot of “10c” dialog through out season, why would additonal images be needed?

Yeah, but at the end of the season, things will have moved past “10c” into future “10c”

Just two more “10c” episodes for things to make cents.

if there was a behind the scenes explaination of why “10c” and not “10s” somewhere;
would the discussion be “10s” enough to split into 2 camps/tents?

I’m glad Discovery is continuing this season’s fine tradition of highly creative episode names.


I’m not a DSC hater, but that is one thing that I have found especially irritating.

Yeah, that is unusual as the first two seasons, especially the first season, had some cool and memorable episode titles.

Yeah, I second what Tiger2 just said. Looking forward to a great finale, but not holding my breath it will happen, especially considering the disappointing last three episodes.

That last episode was primarily filler with a lot of people worrying about how people were feeling. Haha, to put things into perspective, my favorite part of last week’s show was when one of the Starfleet admirals told Burnham not to screw things up! It reminded me of Archer’s friend and commanding officer Admiral Forest saying the same thing in the series premiere of Enterprise. I wonder if the writer’s room did that on purpose? I would be very impressed if they actually know about that line from Broken Bow.

UPDATE – On this International Women’s Day, perhaps I need to be more open minded and appreciate that women indeed bring positive and very different attitudes into the workplace and this should be reflected in the shows we watch as well, including Star Trek.

I’m expecting some overly emotional speeches, lots of tilted heads wearing upset expressions, Burnham whispering, Burnham making a life affirming command speech, some over the top expressions of sexuality that isn’t boy girl stuff to ensure we understand that in the 32nd century you can plunge your wang into anything and vice versa.

Hopefully, the Discovery blows up in the last episode, all hands lost, and this show can be finally put out of it’s misery.

As someone once said, and I forget who, ‘it’s been a long road, getting from there to here….’

You are distinctly and intensely terrible.

Some of what you say is absolute truth, some is inappropriate… The saying comes from the idiot Enterprise theme song.

I just hope they won’t again stand around and talk about their feelings for 95 % of the episode.

Maybe that’s the solution to stop the DMA. After talking about their feelings the whole time, the DMA is annoyed and implodes. If Kirk can talk computer to death…

Don’t bet on it. Even the damn ship has feelings…

Do they write “slomo hero walk into camera” into the script or is that something that is up to the director? It feels like they done a lot of them this season.

Maybe the whole season would work if it could be binge-watched. But their rules of acquisition don’t allow that.
I hope they cut all the filler episodes and filler parts and recut the whole season to a feature film. There are some really good ideas showing really alien and strange new worlds. But the execution is terrible.

I really feel like this season has figured out what the show wants to be. I haven’t been on board with some of it, but I love the sheer amount of well done queer stories and now in the tail end they’re, you know,

caught up
*exploring new worlds!*
Michael still radiates protagonist energy in all directions to the level where she gets /far/ more credit than she deserves, but I think adding Book to the show allowed exploration of a fun Michael instead of the 24/7 sad serious Michael. And I love seeing the bridge crew expanded on.

But yeah. While I haven’t been 100% on board this season- the middle part kinda lost me pretty hard- it’s my favorite season so far. I at least think behind the scenes they know what show they want to make and the work environment is more stable. No more directionless nonsense like season 2. I feel confident saying season 5 will be a good time.

Is it just me, or does Discovery have way too many “Crew walking bravely down hallway side by side” scenes? There’s a photo of one for this upcoming episode, there was one last week, I feel like there have been more than a handful the last 2 seasons. It’s too much, too corny, too cringey. I get that it has become a staple of action films at this point to have one of these scenes, maybe it started with Armageddon, I dunno, but its played out and lame at this point. Please, stop doing this.

And again CBS has chosen the most boring photos possible for their preview.

there are no camera shutters, all digial. aka no snappy shutter photos

the perspective of the backdrop’s hexagonal floor pattern not matching the actual floor’s perspective really bothers me 😄

So, get the latest D&D startrek pre-print that lists “10C” offense./defense rolls?
