Nonsense + EXPLAINATION

Rating: 5/10 (1 May 2020)

I have 6 to this as it is generally ok movie, but is utter nonsense from scientific point of view.
First of all, if something with mass large enough to go thru atmosphere with cosmic speed, impact would be equal to hefty atomic bomb. Think Tunguska event.
If it was a broken starship, sorry, but physics is physics.
As for this genetics nonsense, this is utter bull crap. Take that from geneticist. Live organisms do not change in order, only defects are possible. Also take into account that bio stuff respect thermodynamics And move from higher energy to lower. - No something from nothing.
EXPLAINATION:
Only way this movie could work is if broken alien's spaceship would Crash land, braking before impact. Its nano-machines go try and fix the spaceship, but they get confused and wreak havoc by rearranging everything with everything. The system is centralized, because when alien is burnt, zone falls apart. The alien is real tho.
The only part of this movie that is worth while is part when alien tries communicating. This is realistic, as intelligences differ In their nature, and it might be hard to impossible to understand another intelligent species. The alien obviously tries to adapt and understand, but is killed.
The last part that shows both replica and the (original) female having part of corruption in them doesn't mean much. It might be that just residual nano mechanisms remain.
