Don't have time now to watch the video, but my favourites are those who are evil without magic. What are Maleficent, Ursula, or Jafar without their magic? Those who can control their lead psychologically, those are more realistic and scarier. Think: Frollo, Lady Tremaine, Scar, Gaston, and Mother Gothel (she has magic, but she doesn't use it to control Rapunzel)
I think Facilier has a great song, but is not a well written villain as he has hardly a relation with the lead. Most are related, or have a very close connection to the lead. I think it helps if the villain and the lead are family, as this gives an extra dimension of drama, but it's not necessary. Gaston, Jafar, but also Buddy Pine in the Incredibles are all great villains without being related to the leads. However, these men are all obsessed with their leads, or know how they can be of use to them.
Evil Queen = Stepmother to Snow White
Maleficent = Also a bit vague, but at least she knew Aurora's parents (sort of
)
Lady Tremaine = Stepmother to Cinderella.
Ursula = Banned by Ariel's father, like Maleficent, it makes sense that she goes after the daughter to attack Triton where it really hurts.
Gaston = Belle's suitor
Jafar = Servant to Jasmine's father
Scar = uncle to Simba
Frollo = Surrogate father to Quasimodo
Hades = Uncle + prophecy that Hercules will bring him down.
Mother Gothel = Surrogate mother to Rapunzel
Facilier wants to take over New Orleans, take the place of Big Daddy who is the father of the lead's best friend, and he does that by going after potential suitor and servant of said lead's best friend. A bit far fetched in my opinion. Without Tiana, Dr. Facilier could still carry out most of his plan. She is not part of the plan in any way, she just happens to come by at the wrong moment.
Other weak villain is Ratcliff for the same reason, he and Pocahontas have no connection. I haven't seen the movie in a while, but I even wonder if they ever talk/meet? They have completely separate plotlines. Shen Yu in Mulan has similar issues, and also Hades in Hercules a bit, because Hades knows about Hercules, but not the other way around.
