There oughta be a 4-foot sign at “Captain Underpants” that you stand next to that says “You must be this short to enter.” Speaking of short, this’ll be my shortest review ever; I’m going to sum up the entire movie by telling you the name of a character therein: “P.P. Die-uh-ree-ah-stein Poo-pee-pants.”
I may have spelled that wrong. If you’re between the ages of 7 and 9, you will howl at the plethora of potty jokes. If you are a parent-person, you'll mostly smile wanly and snooze, your soul drifting about in the vicinity of the planet ... (wait for it) ... Uranus—only to be awakened now and again by such things as animated, building-sized toilets.
George Clooney is on record as saying he considers Whoopie cushion-type noises one of the eternal building blocks of comedy.
