Dr. Seuss' worlds make for nice animation material, but skill-wise the Illumination studio wasn't quite ready to tackle it. There are glimpses of creativity and a few interesting moments, but overall it felt too much like some generic US animation feature, with some subpar musical bits and rather poor voice acting.
Uninspired sequel that simply brings back the characters from the first film, adds a few new ones and tries to fill 90 minutes of film with no real story to speak off. The visuals are very colorful and some of the animal behavior is kind of cute, but the rest of it is a real train wreck. A poor USA CG animation, like there are so many already.
