Ed uses a drone to listen in on his grandson's conversation by hovering it outside his bedroom window. Not only do drones not have microphones, as there are generally not many sounds that can be recorded hundreds of feet in the air, but even if Ed had installed his own microphone, it would have been useless over the sound of the drone and through a pane of glass.

User Reviews

An innovative comedy story with great plays
29 August 2020 | by mvahidalizadehSee all my reviews

This is the story of a grandpa who comes to live with his daughter's family. His daughter gives his son's room to his father. The war between the son and grandpa starts here. This is a very nice comedy. I enjoyed watching it. The story is happening in many different locations like home, school, etc. The acting crew was awesome. Robert De Niro was great like always. In my opinion, he is a living breathing book on how to act. Also, Uma Thurman was good in this movie. Oakes Fegley is very talented. We will hear more from him in the future. The story was well-directed. In summary, if you are a fan of comedy, this is a great pick for you.
