Ok so this was either a show or movie. Most likely a show because i remember seeing it in different parts over the course of a few weeks. Basically all i remember is that there is either aliens or some type of supernatural entity coming toward earth. Kids are seen pointing at the sky and chanting “they are coming.” Then in one scene a man walks into the kids room with the wife and kids inside and proceeds to shoot them one by one and then kills himself because he feels hope is lost. The kids pointing start to say “they are here”. Last scene that I remember is of a little boy under surveillance while being possessed and its killing him. Thats all I remember, please help.
