This is a horrible lie that has been perpetuated by people who cannot get over the fact that many Disney sequels are actually pretty good.
I absolutely love The Return of Jafar and Simba's Pride. I think both of them are worthy of bearing the Disney logo. So are: Rescuers Down Under, The Little Mermaid II: Return to the Sea and Cinderella III: A Twist in Time.
I think it is obviously unfair to compare them to the originals, but a lot of people are so adamant about hating them just for the sake of it, instead of actually giving them a fair chance.
What's your opinion on Disney Sequels? Which one is your favorite?
