As Chloe already posted, the movie is GREAT. The best Disney movie of recent. For our video game studies though, 2 NON-SPOILER parts particularly stood out to me.
First, a BA officer from a Halo-esc world named "Calhoun" has an interesting twist to her character: being programmed with the most tragic back-story ever. Backstories were brought up in class, and how they have often been overlooked with older video games. It is wonderful to see the creators of Wreck-It Ralph not only aware of that, but playing with the idea.
I give Wreck-It Ralph a solid "A." Let me know what you think of these ideas once you see it!
