As "The Lego Batman Movie's" hyper-melodramatic opening minutes give way to pure comic madness, Arnett's Batman sings a growly metal song about how awesome he is while delivering effortless beatdowns on an army of villains including The Joker (Zach Galifianakis), Harley Quinn (Jenny Slate), and Two-Face (a cute role reprisal/bit of cosmic justice for unfortunately sidelined '89 "Batman" actor Billy Dee Williams). It's a deliberately and delightfully overstuffed action sequence that really capitalizes on the world's-biggest-toy-collection chaos that made "The Lego Movie" such a visually mesmerizing film. But it's all a feint: The conflict Batman faces isn't really with the combined might of his famous rogues or even with—spoilers, y'all—a collection of imprisoned movie super-baddies including The Eye of Sauron, Voldemort, The Wicked Witch of the West, and the goddamn Gremlins from "Gremlins." No, this dickish loner and emotional recluse has to look at the man in the mirror and ask him to change his ways. And yeah, you better believe Warner Brothers shelled out for three different covers of that Michael Jackson hit to drive this point home in its $180 million dollar movie.
