Hello everyone, you guys have helped me before and I hope you can again.
I remeber watching this movie. A guy comes home for christmas with his new girlfriend for a holiday i think christmas. there is a quarantine and the tv starts giving instructions including offering vaccines. Slowly the tv seems to turn the family on each other trying to prevent them from leaving the house. Spoilers it is revealed that the entire house is blanketed in thick black alien cords that have been using the tv to communicate with them and that this is happening to everyone. In the end the “guy” escapes the house and is the only survivor.
Thank you in advance
