The movie started off visually stunning, every object moved smoothly as if in zero-gravity, it had great compositions, relaxing atmosphere, camera moved slow enough to not cause dizziness, and around enough to give us the feel of being in space. Our characters were introduced to us with great pace, showing little details of their background. Then it went downhill.
The rest of the movie insults the intelligence of all astronauts, all of us viewers, and all space programs. It was breach after breach of protocol, blunders, and plot-holes. Basically, stupidity moved the plot forward.
-- spoiler alert --
After the alien life-form showed aggression, broke a guy's hand, which resulted in him losing consciousness, what do you expect our team of highly intelligent, strictly disciplined, best of the best of humanity, would do?
breaking protocol #1, instead of incinerating the box and containing the aggressive alien, they did nothing. They watched as the aggressive creature took its time to escape the box.
breaking protocol #2, instead of incinerating the lab module, they opened the door, got another person stuck inside, and watched him die too, still not incinerating the lab. Why? for the sake of convenient plot device.
blunder #3 air vents suddenly opened! And it could not be closed! oh no! with a dead guy in the lab, what do 4 of our most intelligent people did? send one person to close the air vent one by one. why are they still not incinerating the lab? help me.
IS all the talk about firewall 1 (incinerate box) and firewall 2 (incinerate lab) just talk? sure, spend 10 minutes discussing firewall 1 and firewall 2 then conveniently forget to do either when needed to move the plot along.
plot-hole #4 dangerous murderous alien who went to hibernation after a minor turbulence at the ISS , is suddenly able to freely waltz outside the ISS in vacuum.
breaking protocol #5 In the event of murderous creature on the loose outside of ISS, our group of intelligent astronauts decided to send one person to die by walking around outside ISS.
Killer alien then attaches to said astronaut walking outside. BIG surprise, like seriously, what did you expect would happen?
breaking protocol #6 At that point, our intelligent astronaut was still trying to save herself, trying to get back into ISS, thinking perhaps the rest of the crew can get it off of her. Only in the last dramatic minute when she is supposed to open the door did she decide, oh, actually, it is better that I keep this dangerous alien outside of ISS, because most likely it will just kill everyone inside if it re- enters. Now we have a cheap thrilling/emotional moment where she sacrificed herself.
plot-hole #7 after killing the astronaut, alien decided to discard the life source it just got: the cooler liquid in the spacesuit and the glucose inside the astronaut's body. Instead of latching on to food, it decided to get back in the ISS. This could still be explained by saying it has developed enough intelligence to know deep space is dangerous, but I doubt after 6 consecutive, stupid plot devices, that the scriptwriter put more thought to it than just "it would be thrilling if it tried to get back into the spaceship now."
plot-hole #8 alien knows exactly how to get back into ISS. Viewers were just explained that there are 6 thrusters where it can get back in.
blunder #9 stupidly burn what little of remaining fuel to temporarily stop alien coming in, and at the same time, get ISS into entry orbit. Just what we should expect from our intelligent astronauts, throw away what little resources they have to temporarily keep a dangerous creature out while moving orbit into earth (sarcasm).
#10 after this much danger and breach of protocol, our remaining female lead astronaut decide it is still not time to announce that they should contain the alien in ISS, and prepare to sacrifice themselves. This leaves our Japanese astronaut to expect rescue.
This expectation to be rescued allowed our Japanese astronaut to accidentally set alien free, kill himself, and kill one random new astronaut.
#11 alien never split itself up to kill multiple targets even though it is a cellular organism.
#12 escape pod conveniently malfunctioned and propelled the other astronaut into deep space. Then conveniently work as intended in pod with alien inside.
#13 alien did not kill astronaut for the whole 15 minutes of him in escape pod. A gruesome body would have deterred the fisherman from opening the pod.
Such lazy script! What a waste of great shots! I left feeling drained, dumb, and stressed. Save yourselves and skip this movie.
