Retired Ed (Robert De Niro) gave up on himself after the death of his beloved wife. Time after time, he finds himself in ridiculous situations, losing the remnants of the former adequacy. The last straw for his relatives was theft and his ugly fight with a security guard in a supermarket.
Ed's worried daughter (Uma Thurman) forces her dad to move into her mansion. The house is large and chic, but the family has many children, so there is still not enough space for everyone. Ed is told to live in the room of Peter (Oakes Fegley), his middle grandson, who does not intend to put up with such injustice, and therefore declares merciless war on his amazed grandfather.
Because of the main characters' fights, other family members also suffer – they are like peaceful civilians during the war. But the supporting characters are not just a background: they help us learn more about our stubborn heroes. For example, Ed also has to get closer with his daughter and her husband, and his daughter (Uma Thurman), in turn, needs to learn to compromise with her adult daughter. The question of the generation gap forms a chain on which the plot of the film rests.
The creators of The War with Grandpa hope to return its former glory to a genre of family cinema, the niche of which has been occupied by animated films and blockbusters in recent years. The material for this was extremely successful – a novel by Robert Kimmel Smith, which has been sold in a million copies. Well-thought-out dialogues and notes written in a beautiful style give out a strong literary source in the movie.
The War with Grandpa is definitely a kind and light project, with an energetic presentation reminiscent of the iconic Home Alone. Robert De Niro and his colleagues' acting performance makes you smile or even think about something important. Thanks to the cast, this comedy will appeal not only to children but also to their parents.
