1930s: "Snow White" (but what else CAN you pick here? lol)
1940s: "Bambi"
1950s: "Lady and the Tramp"
1960s: "The Jungle Book" and "101 Dalmatians"
1970s: "The Aristocats"
1980s: "Oliver & Company" & "The Fox and the Hound"
(I love these two equally, however "Oliver & Company", the very first movie I ever saw in theaters, has a special place with me personally)1990s: "The Lion King", "Aladdin", "Pocahontas" & "Tarzan"
(this was MY childhood and it was a good one for animation..."The Lion King" was by FAR the best...and still is, imo! and as for "Aladdin", I actually liked the sequel "Return of Jafar" even more since it centered on Iago the parrot...ha!!)2000s: "Brother Bear" & "Bolt"
If it's not obvious, I love the animal movies...and also the "movies with a message". Although I MUCH prefer traditional hand drawn animation to computer animation, I did enjoy "Bolt". I'm just a sucker for a dog movie.
Least:
1930s: Well, there's only "Snow White"! All I can say is I don't really love OR dislike this one...it's the one that started it all, so you can't hate on it. I'm not a huge fan of stereotypical "weak princess type girls" though...LOL
1940s: I don't dislike any of the 1940's movies...
1950s: Cinderella...I'm not really a fan of the princess stuff...
1960s: "The Sword in the Stone"...naw, some of this movie was fun...I didn't like the random "evil wolf" that stalked them around though. :\
1970s: No "dislikes" really...
1980s: "The Black Cauldron" was pretty weird...cute pig, though. Ironically, this came out the year I was born. Figures. XD
1990s: "Hercules"...I just never liked the style of this one much.
2000s: "Atlantis", "Dinosaur"
(I agree with those who said there were LBT scenes in this movie...they also seemed to copy from themselves too...was it just me or were some scenes very "Tarzan" and even "TLK"? Not a very original story concept, to say the least)
