1) I don't understand why A.I Robots couldn't attack the Shelter base and was limited to Earth.
2) Terrible AIM for Ai Robots
3) Terrible Acting, it was easy to see that Korean Actors and Actresses weren't used to such genre and the way they spoke wasn't natural but but over doing it.
4) I'm a firm believer that good sci-fi movies are based on good science (Interstella, Prometheus, Starwars, Star Treck, Lost in Space and etc) and this was not based on good science and more like a fantasy with none of the science making sense.
5) This was just bad as Seung-ri-ho (Victory Ship) by Netflix. I wish Netflix reads the plots synopsis more thoroughly instead of focusing on high value directors and cast (I mean isn't that what netflix was all about??)
6) As Korean American I think this may be a little step up for Korean Cinema but hope that they work harder on research and devlopment.
