Some people loved this rendition of Lewis Carol's work, others completely hated it. It was by no means a stunning success. I could spend the next several lines explaining what went wrong and what went right, but I won't. This isn't that type of movie.
I recommend this for a very simple reason. The movie is full of great talent. Great performances? Not really. But great talent. The enjoyment of this movie is watching some of the true greats in playful roles. If you watch this expecting great acting performances and great cinematic moments with inspiring music then you are a fool. It was never meant to be anything more than a delightfully fun experience with great moments. (Sammy Davis Jr. as the Catapillar is a great example.)
I can't describe this any other way than to say that Harry Harris got some of the most recognizable faces of Hollywood to put on stupid costumes and act crazy. Even if you don't recognize many of the names on the cast list you should watch it anyways. Several faces will be familiar without your knowing their names.
My major criticism (and warning) many of the songs are very hokey. In some scenes its damn annoying. Most people who demonize this film attack the music first and hardest. Its up to you to sit through the musical numbers you don't like and enjoy the rest of the film. IF you accept this adaptation for what it is and watch it for the right reasons, I guarantee you will be pleased you spent the time.
