I just finished watching stowaway on Netflix and if I was to sum it up in a few words, it would be that it is boring, fucking boring.
The plot is nothing special, space mission to some planet which in this case is Mars, mission goes wrong, crew tries to fix ship, shit gets out of hand, crew makes sacrifices, blah blah blah.
Here is a trailer of the movie to get an idea of the plot
Anyways, the movie as I said is pretty boring, even the action scenes are boring as fuck. The acting is nothing special and it even tries to copy Interstellar here and there in the cinematography and fails miserably.
Overall, it's not a terrible movie but you can live without it. I guess it's an okay watch if you have run out of options on Netflix.
I will give it a solid meh out of 10.
