Review: 'The War with Grandpa' is dated, fails to make a connection
Robert De Niro, Christopher Walken, Cheech Marin and Jane Seymour walk into a trampoline park. Unfortunately, that isn't the set-up. It's the punchline of "The War with Grandpa", a kid-friendly comedy that skates by with gags that find De Niro, the grandpa of the title, slipping on marbles (obviously, accompanied by the line, "He's lost his marbles! ") and pretend punching himself in the bathroom when his shaving cream is replaced with foam sealant. And those are some of the better parts.
