I guess I should be happy that Hollywood managed to make a children's movie that is actually rated G, free of flatulence humor, and reasonably entertaining, but I can't get excited about this one.
On the plus side, this Dr Seuss story is generally seen by prolifers as one with a prolife message. However, the author's widow has been so hostile to that message that I can't feel good about spending my money knowing that a portion of it will be passed on to her. Moreover, contrary to all reason, the screenwriters managed to make the villain of the piece a home schooling mom, of all things.
While it has good computer animated graphics, including impressive realizations of the jungle, Whoville, and their denizens, the simple story doesn't stretch to feature length without getting thin, like butter scraped over too much bread, as Bilbo Baggins once said.
So, if it's in the neighborhood, you've nothing better to do, and your kids want to see a movie, you could do worse. On the other hand, unless you really love computer animated graphics, you may as well just put it on your Netflix queue for later.
