“The Lego Batman Movie” (*** out of four) was a fun animated entry in the “Batman” canon about the Dark Knight (voiced by Will Arnett) struggling to eliminate crime from Gotham City while struggling to raise a young boy named Robin who he adopted and trying to sort out his own psychological and identity conflicts from his youth. Story has its ups-and-downs but is so visually spectacular and at times unexpectedly sharp and funny that it’s entertaining for kids and for Batman fans. At any rate, it’s much more fun than last year’s “Batman vs. Superman.” Rosario Dawson provides the voice of Batgirl, Zach Galifianakis voices the Joker, and Conan O’Brien of all people is the voice of the Riddler.
