Wow, Russian movies are turning out to be pretty good

This is a pretty good story.

It is a little choppy and disjointed, but an original story and script,
and very clever. Not political.

The alien guys with the peculiar looking mouths were a bit hard to
take - maybe they could have done the alien's make-up a bit better,
but I watched it, and it was a solid SF action movie with decent
effects and a good plot.
