As someone who has only known the Latvian version beforehand, the original one makes a lot more sense and I feel like this is gonna be a trend for all three Soviet versions. Certain explanations for some events are just left out, like why does a black hole suddenly appear or why does Indrikis just sacrifice himself at the end for no apparent reason, it's almost comical. All of that makes the Latvian version feel much more random.
While the original version was more somber, which I liked very much, the Latvian version was more jolly and lighthearted, and what's better is up for taste I guess, just like the voices, for example, whether you prefer Receklite's more ghostly laughter in the original or her more seductive moans in the latvian version. What I do prefer in the latvian version is the more extensive use of voices for the characters, it made them feel more lively.
Also it's a shame that Daina and Agnis were cut from the series, I liked them, and I would have liked to see more of the Human civilisation.

I have to wonder if they were cut because they were too difficult to animate, since commercial costs would've become a big consideration in the 1990s. Apart from perhaps Indrikis XIII himself, they seem to be visually the most complex characters (and they can't be morphed out of shape as much as Indrikis sometimes is, because they're human and viewers would notice it more).

And/or maybe because it was harder to avoid having dialogue if you've got humans there.
