I don't know how many cold war films were made where invaders took over common folk. "The Invasion of the Body Snatchers" is probably the prototype. This one borrows from that and a host of others, including the series "Stranger Things." Because the character of Charlie is so well drawn, this works. It would seem that the fatal flaw in the aliens is that they need host bodies. Charlie could have been killed at any time, but they wanted to assimilate him. There is good suspense and some interesting kid characters. The closeness of Charlie and his father makes his task so much more dramatic. The cinematography is very good with some quite positive special effects. Greg Kinear as the father is certainly quietly threatening. We can only wonder what will happen next.
