Starting with a very good idea, it fails all scientific facts

Rating: 2/10 (24 October 2017)

It is truly a shame that an original idea was wasted by so many plot holes, specially scientific ones.
The original idea: a single cell organism that can perform every somatic cellular function, and group itself into a cooperating multi-cell organism. That is something plausible that could be exploited with a vivid imagination. But it wasn't.
It created some moments of tension, but that was it. As long as you don't think, or don't know, about the facts.
The bad. Things that are just not possible, defy logic or fact.
Catching a runaway ship with an arm made to operate in micro-gravity... It would just break it into a million pieces.
The alien "just knows", without anybody teaching him, that a glove can be pierced, and what he can use the rod to pierce it. How does the alien know the properties of rubber? And the concept of piecing and what objects (concept of pointed object) to use for doing it?
Fire resistant alien... unbelievable. After using fire all over the place, only when the torch is left floating alone does the fire alarm start ringing... duh!
Fantastic isolation ("firewall") on the test chamber, as it vents fire (and any contaminants) into the rest of the space station. Shouldn't it vent it to space?
It is "inconvenient" that the test chamber isn't detachable from the rest of the space station. Otherwise you would eject it and... case closed.
How the hell does the air extraction system get connected to the coolant system? On the ISS the coolant system uses ammonia, something that is deadly to humans... but not for the alien that eats it all. By the way, after eating the coolant, the ISS never starts to get warm. Unneeded system, I guess.
Failsafe mechanisms would prevent Sho from opening the hatch, manually or not. After that, decompression from the ruptured seal wold space the alien. Nope.
The final part was the worst.
Soyuz capsules have a 3 passenger capacity, not 1! How the hell did the alien learn to pilot a spacecraft? And the Soyuz does not land on sea, like the American capsules Mercury, Gemini and Apollo. They land on the ground on Kazakhstan. Kazakhstan, like the country that launches the Soyuz rocket, and where the Baikonur Cosmodrome is.
As I said, an very original idea wasted... due to laziness.
