Since Toy Story 3 is in theatres, it's rather knee-jerk to compare Despicable Me to the animation giant. But you shouldn't. Despicable Me doesn't have the heavy, dark tones of the final Toy Story and, therefore, is probably better suited to smaller children. As with the best family films, though, adults will love this story as much - if not more - than their little ones.
And here's why. It is incredibly rare to see a single dad portrayed in such a positive light. While Gru has an admittedly "bad" vocation, there are unbelievably sweet moments between him and the three children, probably aided by the juxtaposition of tiny girls to a large, "bad" guy.
The nepotistic supporting cast from Saturday Night Live (even Jack McBrayer works for Tina Fey) is fantastic. One pleasant surprise was from Gru's minions: they did not steal the show. Not that they should've- the little yellow guys were funny and entertaining, but one would expect from the previews they would ultimately be the best part of the film... and I'm happy to report that wasn't true.
Despicable Me is LOL funny throughout, warm, goofy, and will not disappoint. I'd say you're a despicable parent if you don't take your kids to see it immediately.
