Since this topic is pretty general, I'm going to take the liberty to just write WHATEVER it is that comes to my mind about Beauty and the Beast.
-----
NITPICKINESS--
-Whenever it comes to the bar scene, I don't know why, but I never REALLY WANT to watch it, but since its part of the story, I still do. I still enjoy it, but don't find anything about it particularly special, even though the gags with Lafu are pretty funny.
-Some scenes bother me when Belle doesn't look quite ON MODEL, like the part where she talks to the butcher and also when she says "You always say that" to her father, her face is a bit smooshed. There are also a few instances where Belle looks shorter than she should be.
-The horse's, Philippe, hair isn't blowing in the wind as hard as Belle's when she's taking the wagon off of him. ( I need to check this later)
-I've watched the "Belle" scene over and over, since it's the very first part, since I'm really interested in the animation technique I watch it slowly, there's one part when Belle backs up from Gaston and her head jerks back quite quickly, not very noticeable, just an observation.
-I like the "Human Again" song, but am not content with Mrs. Potts voice. I didn't buy the fact that the rose was out of the West Wing and that the Beast would put it on a walking table. Certain things about the scene didn't fit, like when the characters go off, and there are sound of hooves and cows mooing. The "no walking on grass" sign was also out of place.

MUSIC AND SOUND--
-I absolutely LOVE the score, there is not one song in the whole movie I don't enjoy, the lyrics are perfect. Even the background tracks are beautiful, though at times I think it would have benifited the emotion of some scenes if it were louder, like the wolf chase scenes, the fight between Gaston and the Beast, and particularly when the beast dies.
-----
ANIMATION--
-The animation is amazing. This is the best animation style, in my opinion, of all the Disney movies. Aladdin is great but VERY stretchy, squashy. I love the more realistic feel of Beauty and the Beast.
-The way EVERYTHING is choriagraphed in "Belle." It's amazing how much you miss if you only look at the main characters.
--LITTLE THINGS I'VE JUST RECENTLY NOTICED--
Watching the film at a slower speed can also be rewarding, its funny to see a character you never really saw before, particularly the characters that are only on the screen for a few seconds.
-There's a kid chasing the pig, then the pig chases him back, it's funny to see his facial expressions. Also the shepherd chasing the sheep, I never really knew what he looked like before.
-While Belle is at the fountain, there's a woman cleaning her clothes, when she hears Belle sing she looks up at the sky wondering where the sound is coming from, then she sees Belle, and gets annoyed. Too funny.
-I just noticed this a few days ago, but the arrows on Gaston are always moving in the container their in, very subtle, but makes the movie more alive.
--FAVORITE BITS OF ANIMATION--
-They may be only a few seconds long, but I am totally in awe of the turnarounds in the movie. When Belle slides on the rolling ladder in the bookstore, when she jumps off the wagon just before entering the bookstore, and my personal favorite, the part where Belle sings "There must be more than this provincial life" the camera does a complete turnaround.
-Another one of my favorites is when Belle goes around the back of her house after being proposed to by Gaston. She then sings "Madam Gaston,.... etc" the animation is superb.
-The transformation- cool, including the transformation of the objects into humans.

SILLY KID MISUNDERSTANDINGS--
When Chip bubbles up the tea, Mrs. Potts scolds him, but THEN Mrs. Potts says "That's a brave thing you did". I always thought she was still talking to Chip, saying his bubbling was brave when in fact she was talking to Belle, of course.

-----
OTHER THINGS--
Is Gaston, in fact, the one that is responsible for the Beast returning to human? Since it seems the state the Beast was in meant Belle would have never returned to him. Hmmm...

I'll probably update my post later, since I've only really "studied" the movie up to when Maurice leaves.
There's so much more to go.
