Today I saw The Cat in the Hat. It was fairly interesting, although it did get off to a bad start by making fun of people who use hand sanitizer and make to-do lists that schedule the making of future to-do lists, both of which I do.
The movie explored certain aspects of the story that were neglected in the book. For example, we finally learn something of the cat's origin and why he is so different (large, bipedal, can talk, wears a hat, has access to advanced technology) from most other cats. Apparently he comes from another world and can visit ours through a dimensional portal. (Perhaps we will learn something similar about the talking goldfish in the sequel.) The movie also makes clear that the cat had pre-planned most of the occurrences as an attempt to teach the children a lesson.
There were also some additional elements to the storyline, such as the mother being single and employed, the trip into town to rescue the dog from the evil boyfriend, and, of course, the fire-belching toilet. Doubtless, such additions will be embraced by fans and added to the Seuss cannon.
Unfortunately, the movie also introduces some unanswered questions. How did the mother finally get home after Thing 1 and Thing 2 ate her license and registration?; how can cupcakes be purple when none of the ingredients (which include broken glass) are?; and most significantly, how can a single cat be both spayed and neutered?
