The Lego Batman Movie is about as much fun as you make it out to be. Will Arnett is ideally the perfect voice for the cape crusader because he always plays an arrogant character who never quite realizes there are other people around him. There are a bunch of laughs throughout the movie, but the absolute best parts are when the movie pokes fun of all the other Batman movies and characters. For kids, this will be a great story with all kinds of funny spots, but for adults some may get disappointed for the lack of depth in the overall story.
