Mrs. Salad picked up this DVD the day it came out. This was my favorite movie from last year. I still feel the same way now: it's the kind of movie that makes me want to fall to my knees in sheer gratitude that I live in a time and place that produces works like this.
The Extras disk is crammed with good stuff; I haven't watched it all yet, but the highlight so far is "Jack Jack Attack", an animated short showing what happens between Kari, the Parr's babysitter, and Jack Jack while the rest of the family is off saving the world. Kari's "mental stimulation" of Jack-Jack causes him to discover his multiple superpowers; Kari's less than thrilled with this.
Usually DVD "extras" are pretty predictable, but these show the inner workings of an incredibly talented bunch of people doing what they enjoy, at the peak of their game. So: highly recommended.
