Zootopia delivers the genre’s requisite barrage of quick-hit puns and pop culture riffs ( a rat mobster modeled on Don Corleone) , but the funniest moment comes when Judy goes to the Department of Motor Vehicles to run a license plate and gets her patience tested by a sleepy, slow-as-molasses sloth slumped behind the desk ( Raymond S. Persi) .
Zootopia’s message of tolerance is a noble one. But it’s loopy moments like that that give this modest film its magic.
