Underwhelmed. It works well enough without the 3-D, but you can definitely feel that something is missing (I never got to ride the 3D version, but I could sense its removal). It needs more sets and props as the majority of the attraction is just screens with little theming.
My favorite scene is the pantry, where some of the ride vehicles hide the way real rats would. This is a cute ride that has adorable ride vehicles with personality (I honestly think the ride vehicles are the best part of this attraction). I wouldn't wait longer than 30 minutes to ride this.
