Yeah, calling them sequels and stuff is unkind. The games are awesome by the way, and is simply someone elses interpretation of Alice in Wonderland.
Just wondering... Have you read the book? Can you really compare the disney movie to a book, considering they change everything around for a happy ending. Did you know in the original version of the little mermaid, Ariel was supposed to die, not marry her prince and live happily ever after. Many Disney movies based on other things actually make things 'lighter' than they should be.
In fact, in the hunchback of notre dame the gypsy girl is supposed to die, and quasimoto (No clue how to spell it XD) climbs into her coffin and stays there, buried, until he dies.
