The first film was dark, well done, awesome and overall one of my all-time favorite movies. The sequel however was a pile of crap.
A large amount of the dark theme was removed. The villain of the film Sarousch, was an egomaniac and was nowhere near as awesome a villain as Frollo. While Frollo was dark and complex as well as the Minister of Justice granting him great political influence, Sarousch was simply put: a vain and narcissistic thief using a circus as a front. The animation, like all direct-to-video films, is weak compared to the first film. And unlike the first film, all the songs in this film are lazily done, soulless, annoying, and forgettable.
The only redeeming thing about this film is Quasimodo finally gets a love interest by the name of Madellaine who was Saousch's assistant when he performs. She eventually turns on him leading to his arrest.
Overall, this film is unbelievably terrible and an insult to a great movie. Avoid this film at all costs.
