This is probably one of the best examples of making a previously 2d only movie (with some already strong field of view elements) and making it 3d. The opening of the movie gave me goose bumps just as big as the first time I watched it. Luckily I'm old enough to remember the first time I watched this movie. Every one I know has a tally of how many times they've watched The Lion King (my cousin did 8 times in theatres first time around), and mine just went to 27 (now 2 in theater, 3 on TV, and 21 times on VHS). If I had the money I'd go and see it three more times just to match my current age. The Lion King essentially defined an age of Disney Movies that started with The Great Mouse Detective and and continued all the way through until now. There's some really great movies out there, but Lion King set the bar for hand drawn feature animations a little too high, and adapting it for 3d just made my week.
Passed Mustard? Wholeheartedly yes.
Also The Great Mouse Detective is the dawn of the modern age of Disney Animation, with it's use of computer generated backgrounds and full scene computer animation. Black Cauldron was the end of the Classic Age of Disney Animation because they used the multi-pane camera and only a bit of computer assistance for tracking movement, well that and I was 5 when it was released.
