In a way I almost want to up the score by a point or two just for being exactly as bad as I imagined.

There are honestly aspects of this movie that I like. De Niro's Ed doesn't want to be there. and the kid Peter hates losing his room. This is a childish thing for him to hate but he at least is a child. The real curiosity is why he has a giant room to himself while his sisters one in elementary school, and one in high school are sharing a room. It's a ridiculous arrangement. But Peter with zero tact or shame openly hates on his grandfather for "stealing his room". This shows how poorly he's being raised that he never talks about why his grandpa is moving in and no one talks about why grandpa is moving in to him. The kid just takes it personal and is constantly very publicly announcing his displeasure. It's weird. But the first thing I like about this movie is that Grandpa Ed doesn't take it seriously. It's a child acting childish why would you take that seriously. It's one of the most realistic aspects of the movie. He just ignores him. Beautifully.

But eventually the movie has to happen and Peter is too childish to not just straight up assault his own grandfather so Ed devises rules of war that they have to follow. All reasonable measures about keeping it one on one. The "pranks" or "attacks" in this movie aren't worth speaking about for the most part. There's the one where Ed retypes Peter's "What I did for summer" homework and the kid has to read out loud embarrassing sentences in front of his class because his teacher insists that he keep going and Peter is too much of an idiot to lie and make up what he did over the summer. Seriously it would have made much more sense if someone else had read the paper to the class. The rest of the pranks are literally 1 step up from that. They're boring. They're uninteresting and Grandpa as the adult has the better pranks. It all culminates in a final competition of Peter's choice. He chooses the sponsored sport of trampoline dodge ball brought to you by whatever that place is called.

It's at this point that I dismayed that we were only 50% of the way through the movie. What more could possible the movie have to say? Turns out... nothing.
