This is one of my favorite alien movies I think the acting was good because they were more curious instead of just ignoring certain things you can see the fear when they don't understand what's happening. I liked that the boy hated synthetic humans because one killed his mom I also liked how the one girl seen the synthetic human as her brother instead of just a thing I loved the detail in things an how they looked more real an the hybrid human was a twist and that was really cool to see. I hope they make another with the girl an the synthetic human brother. THIS MOVIE IS SO WORTH WATCHING. My partner says it sucks an everything about it sucks I'm a big alien fan don't listen to people when they say movies suck decide that for yourself.
