There are certainly not many G rated movies any more. When I was growing up, back at the dawn of time when the earth was still cooling, there were plenty of them, and the movie makers never wanted to get even an R rating. Pg 13 was as far as most dared push the envelope. One of the great pleasures of being a child in the 50s was that reading was actually emphasized as important, and was rewarded. Those Weekly Readers got you somewhere, and the library was a regular and popular destination for the young. Certainly some of the most popular books children enjoyed reading in that era, and later were the some 40 books of Theodor Seuss Geisel (1904-91). He was famous for his zany characters and his even more entertaining drawings of wild and woolly characters. He made the Disney characters look like Vanilla Ice Cream, and even the Looney Tunes Characters were outdone from time to time. It is all the more amazing that it took so long for some of his classic children's books to be made into movies. Of course his most famous books were 'The Cat in the Hat' (and its sequels) 'Green Eggs and Ham' and 'How The Grinch Stole Christmas'. One of the most creative aspects of his books were his clever rhymes. Indeed most of his books were rhymes from start to finish. I have no doubt that these books affected me early on and were one impetus propelling me into writing poetry that rhymed. Rhyming was made cool by Dr. Seuss.
But there was much more going on in Geisel's books than just entertaining rhymes and fascinating animal characters. Geisel had some interesting educational and philosophical messages to convey, and 'Horton Hears a Who' is a perfect illustration of this tendency.
What most will not know about Theodor Geisel is that his Dr. Seuss books came at the very end of a long and interesting career as a writer, political cartoonist, satirist, writing of documentaries and much more. Here is one summary of what happened in the early 50s to prompt the writing of these books, courtesy of Wikipedia---
"At the same time, an important development occurred that influenced much of Seuss' later work. In May 1954, Life magazine published a report on illiteracy among school children, which concluded that children were not learning to read because their books were boring. Accordingly, Seuss' publisher made up a list of 400 words he felt were important and asked Dr. Seuss to cut the list to 250 words and write a book using only those words. Nine months later, Seuss, using 220 of the words given to him, completed The Cat in the Hat. This book was a tour de force—it retained the drawing style, verse rhythms, and all the imaginative power of Seuss' earlier works, but because of its simplified vocabulary could be read by beginning readers. A rumor exists,that in 1960, Bennett Cerf bet Dr. Seuss $50 that he couldn't write an entire book using only fifty words. The result was supposedly Green Eggs and Ham. The additional rumor that Cerf never paid Seuss the $50 has never been proven and is most likely untrue. These books achieved significant international success and remain very popular.
Dr. Seuss went on to write many other children's books, both in his new simplified-vocabulary manner (sold as "Beginner Books") and in his older, more elaborate style. In 1982 Dr. Seuss wrote "Hunches in Bunches". The Beginner Books were not easy for Seuss, and reportedly he labored for months crafting them."
With this background were in a bit better position to evaluate what Seuss accomplished. For one thing he was the champion of the little person, and this comes through so very clearly in 'Horton Hears a Who'. Even small people are people deserving of respect and love. This same book also reveals Seuss' satirizing of those who don't believe in anything bigger than themselves, or anything that they can't see or touch. Every chance he got, Seuss ridiculed cynicism, and championed the use of the imagination to create solutions in life. He had reason to believe in such things since he had to support his family through the Great Depression by his wits. He drew ads for General Electric, the Saturday Evening Post, Vanity Fair, Life Magazine, NBC, and even Standard Oil during that period of his life. He was a master of ridiculing those who took the fun, joy, and excitement, and sense of wonder out of life (see 'How the Grinch Stole Christmas').
This movie, unlike say 'Ratatouille' lacks creative spark, unlike Seuss' original book. It relies too much on motion and action and too little on the intellectual side of Seuss' work. The characters are likable enough, but they certainly do not capture the heart or imagination like other such films (say for example the 'Lion King', or the 'Emperor's New Groove'). As a holiday movie, its the best there is in the theaters just now, and is not likely to offend any one, but it is also unlikely to make many see the larger human values that Seuss sought to encode into his work, which is a pity. It would have been nice as well if there had been a better sound track for this film as well. All in all, I give this film a B- compared to the better work in its genre. Not bad, but it could have been much better.
