Peter is thrilled that Grandpa is coming to live with his family. That is, until Grandpa moves into Peter's room, forcing him upstairs into the creepy attic. And though he loves his grandpa he wants his room back - so he has no choice but to declare war. With the help of his friends, Peter devises outrageous plans to make Grandpa surrender the room. But Grandpa is tougher than he looks. Rather than give in, Grandpa plans to get even.
Was this movie 100% formula in every way? Yes. Was it a Dennis The Menace/Home Alone wannabe with Robert DeNiro? Again - yes. But was it a watchable family movie still? Somehow . . . . . . yes. I'm not saying its a must watch by any means but I was okay watching it and not itching to turn it off and for this movie I would call that a success.
I would somewhat recommend families checking this out. It is beyond predictable in every way but still was a somewhat decent watch.
