Unexpectedly great film

Rating: 8/10 (29 March 2017)

Spoilerfree: The film stands out with a fine quality of camera work, acting, design, shock moments, characters and a solid plot, which also gives you a nice and honestly brutal ending. It is just a very well made film that captures an immersive, dense and hostile atmosphere.
Spoilerstart: One question I kept on wondering about are the electroshocks against "Calvin". I think this is a crucial element of the plot. - First possibility: Calvin was pretending to be "asleep" which makes a clever and predator-like (not evil) life-form out of him. - Second possibility: Calvin was "honestly" asleep, they attacked him (later on also with the fire) and he got into a defending mode that evolves into attack and killing. - Third possibility: Calvin was "honestly" asleep but always up for attacking everyone, woke up because of the shocks and followed his instincts.
Why is this important? Because it arises the question in which context "life" itself is hostile against itself. Perhaps the scientist are the enemies of "Calvin" - which the film remarks at some point as well. Considering humans the film makes hints concerning war on earth, the situation of mankind and our aggressive behaviour - things we are already doing without any alien influences. The biologist (who gets his hand broken) once makes the statement that he might also be able to answer the question about the "sense of life" just by raising this cells in the box. Well, by doing so the whole movie answers this question (war and conflict) in an cynical way (by which the ending is the perfect brutal topping). In a way it is possible to see the situation on board of the ship as an reflection of the human situation on earth. Just that there are humans against aliens and not humans alone fighting against each other. But when we change "humans" and "aliens" just to "life" and then look at the alien and the scientist as living species it is not a big difference anymore - and we see the life in conflict with itself.
