I think 'Sleeping Beauty' is a considerable disappointment after the wonderful 'Peter Pan' and 'Lady and the Tramp'. Released in 1959 it is generally regarded as the end of Disney's second classic period. From here on, Disney would see budget and staff cuts for the next few decades, and even as early as this, it shows.
Compared with the preceding two features the background drawings are cartoony rather than sumptuous, which isn't nescessarily a bad thing, but here it doesn't really work. There are some rather jarring 'special effects' early in the film, and the style of the movie, whereas it earns points for experimentation, just looks rather cheap compared with what Disney had done through most of the 1950's. And then there are the characters. To describe Aurora and Phillip as 2-dimensional would be flattering. Phillip's horse has more personality than he does, and he's virtually useless to boot. He even needs the three Good Fairies to get his cape untangled from some thorns for Heaven's sake. Added to the above, the whole thing just seems old-fashioned even compared with the movies Disney had been making over most of the previous ten years. In fact when I was a kid, I used to get this movie confused with 'Snow White'.
Ok, that's the bad. On the plus side, the three Good Fairies are delightful characters - in fact without them the film would have been pretty dull in my view. They SEEM like they ought to be comic sidekicks, but for all intents and purposes they're the main characters. Compared with them the hero and heorine are cardboard cutouts who get very little screen time. Maleficent is a good, if not particularly unusual villain. The quality of the actual animation is very good. The general storytellling is pleasingly paced, and despite the fact that it comes across as a step down in almost every department, the movie still works pretty well simply because it was a step backwards from such a lofty height.
I tossed up between two and a half and three stars for this one. I eventually decided it was closer to three, but really I just don't find this a tremendously engaging film, either by modern standards, or the standards of Disneys own classics.
Though it's a bit contrary to conventional wisdom, I think the next feature, '101 Dalmatians' was an improvement (despite the budget cuts), but after that it would be a long time before many people other than their advertising department used the words 'Disney' and 'Classic' together.
Not a bad movie, but if you're exploring the Disney back-catalogue, don't start here unless you've just got a thing for fairy-tale 'Princess' films. It might still get 3 stars, but nearly everything they'd done up to this point was better.
