I am one of the few people around whom still like Steve Carell, but for those who hate Carell you are in luck again. Since this is an animated movie, you won't have to deal with seeing Carell, and because he plays a guy with an accent, you won't recognize his voice.
Do remember going in that this is a kid movie, and there is a simple plot and simple solution to the movie. On the other hand, there is humor in this that adults will find funny. It goes right over the kids heads and into your mature noggin.
The minions are the funniest thing in the movie. They need to add camera time with the minions.
