This week on "Justin Hall At The Movies," I'll be reviewing Robert De Niro as he goes one-on-one with his grandson in "The War With Grandpa." Robert De Niro is no stranger when it comes to playing grandfathers. He's done it before in the Meet the Parents movies. Then he did it in the atrociously laugh-free Dirty Grandpa and now he plays another one in The War With Grandpa.
