Usually I have issues with your tendency to slap three stars down on the majority of Powell's animated scores no matter how brilliant their highlights (come on, how can a score with as much funk and energy as Robots not earn higher, especially considering the way it still manages to juggle four major themes?). But I think Powell might have phoned this one in somewhat (forgivable, considering the film). It's a definite step down from his majestic effort for the first film and doesn't really bring anything new to the table (unlike Kung Fu Panda 2). Still enjoyable enough, but when the cue you find yourself repeating most often is the cover of "We Are the Champions" (the first half, anyway, before the polka starts up), you know the score isn't anything special. Even Rio, by no means his best score in the genre, had some memorable themes and a couple decent action cues to salvage.
Still, I think Powell deserves a nomination for composer of the year for the awesome duo of Kung Fu Panda 2 and Mars Needs Moms alone...I hope you don't neglect him there, Christian.
