I’ll take that over a black hole with mass under a pound instantly sucking in an entire planet.
The trouble with having lots of non-humanoid aliens is that the audience will have trouble empathizing with a creature without relatable facial expressions, and writers will have trouble creating drama with characters who can’t have sex with the other characters.
Truly non- humanoid aliens work better in “Hard sci-fi” than they do in space operas.
As I remember, what used to be be considered the greatest science fiction space operas of all, E.E. Smith's
Skylark series and
Lensman series, had plenty of human aliens but also plenty of non-humanoid aliens, some of them very bizarre by human standards.
As I remember, there are a lot of nature movies and shows where audiences sympathize with non humanoid Earth animals, and movies about humans and their pets. As I remember, society has a lot of categories of relationships where it is considered inappropriate for persons in those relationships to have sex, and there were often rules and even laws forbidding the depiction of sex or romance between people in those categories of relationships, and yet a number of stories, novels, movies and television episodes managed to depict dramatic situations involving persons in those relationships.
Hence, the stupidity of red matter.
It is illogical to flatter red matter by calling it stupid. It is unknown whether the properties of red matter allow it to be organized into nervous systems and brains. Even if red matter can be organized into brains, only a tiny, minute fraction of it would be, as is the case with our type of matter. Therefore, calling red matter stupid is vastly exaggerating its intelligence level.

The holodeck in TNG is at least 600-1000 square feet, with at least a 20-25' ceiling. I believe they only built a miniature set of it, and composited the actors into it.
I imagine that TNG has many holodecks of varying sizes. I'm not sure what the highest numbered room is, but I know they mention "holodeck five" in an episode. On a ship so big and empty, there could be 20 holodecks for all we know.
Voyager only had two, and they were identical in size to each other, and they were an actual set(and smaller). The
DS9 holosuites were very small, and it's hard to imagine playing baseball on it, with everyone spread out, while still being able to see each other. It seems impossible.
I like to think that holodeck technology is not something humans invented(unlike Warp drive, transporters, phasers, etc), but some other alien race of the Federation.
A 600 square foot room would be about 24.5 by 24.5 feet if square, or 12 by 50 feet, etc., and a 1,000 square foot room would be about 31.6 by 31.6 feet if square, or 20 by 50 feet, etc. And they seem like rather small spaces to walk around in.
An
Enterprise episode had an example of alien holodeck technology, while a TAS episode had a recreation room on the
Enterprise with early holodeck technology. But about 90 years later in "Encounter at Farpoint" Riker was amazed by the holodeck on the
Enterprise D.
