What I can see is an unimpressive cartoon with very limited imaginative material. A flying cow - that's brilliant! A superhuman intergalactic villain that walks about in an ugly coat with a turned-up collar and resembles a poor pensioner - that's fantastic! A rectangular parallelepiped that jumps and changes colour - that's groovy! A fictitious bird that looks like a slightly tuned-up parrot - wow! A couple of evil robots (blocky and with an AI of a child) that can be easily defeated with the help of good old judo - that's outstanding! You can continue this list yourself. Get over it, this cartoon was good for its time (and for its place - the whole idea was the winner in those grey USSR days) but now it is almost unwatchable to me.
Not everything is junk of course. I like the idea of mirror-flowers that have memory of their own. One of the landscapes presented is quite picturesque. And the space suits of the main three characters are very believable and have a nice colour scheme. Apart from these features there is nothing else to admire.
There was a proper sci-fi animation film from those days but unfortunately I do not remember the title and the country that made it (it started with some swift vehicle running through the landscape somewhere on a distant planet and continued delivering mind-blowing landscapes and creatures). One day I hope to find out what it was.
If I want a sci-fi animation film, I go for a Japanese flick ("Last Exile" IS great, "GITS: Stand Alone Complex" IS impressive). Usually Japan does not disappoint: tons of fresh ideas are wrapped up in an eye-candy jacket of lines and colours.
As to this very cartoon... It's passable at best. I can only agree with the opinion that it really shows potential. And I can only wish it had been made in a different way (more imaginative characters and creatures, better dialogues, detailed robots, menacing villains, etc.).
It is a drag (I would recommend this one only to those who have fits of nostalgia) - 4 out of 10 from my side is an objective mark, I think. Thanks for attention.
