Filled with so many “I wonder how they did that” moments—a stew of Looney Tunes, video games, and adventure movies (the last act certainly evokes any of your favorite “sneak into the enemy lair” setups, from Star Wars to The Incredibles). I loved the low-budget ingenuity, particularly the use of animation and plushies (!). Big beaver brawl setpiece truly a cinematic achievement. The perfect chaser to There Will Be Blood, because that was one milkshake that left me with heartburn.
