I personally fear a sequel
As much as I LOVE Disney, I have to say they aren't 100% successful with sequels. They make very good first movies, they don't need to make sequels because they leave the ending to the first perfected. Wreck-It Ralph, being a super successful movie and a personal favorite of mine, I fear just how they're going to continue off. And its pretty obvious, Disney gives love interests to everyone unless they're a villain or a super minor character. So I'm betting that to everyone's dismay and mine, Ralphie's getting a love interest who will be this pretty, girly, angelic, beautiful little lady who's all smiles and the "You HAVE to love me!" character. I don't know about anyone else, but if she suddenly was his love interest in the sequel I'd hate her more than I'd love her xD
Sooo.. I'm frightened at the idea of a sequel, but if Wreck-It Ralph DOES have one, I only hope the plot is awesome!
