Despite the title, this is actually the fourth Lego movie, following 2014’s introduction and two subsequent spinoffs—The Lego Batman Movie and The Lego Ninjago Movie. Set five years after The Lego Movie, live-action Dad (Will Ferrell) and his now-adolescent son Finn (Jadon Sand) are once again playing with the popular construction toys. But now Finn’s little sister Bianca (Brooklynn Prince) joins them, and Bianca’s bedazzled Duplo-blocks create chaos for Bricksville’s animated inhabitants: Emmet (voiced by Chris Pratt), Wyldstyle Lucy (Elizabeth Banks), Batman (Will Arnett), MetalBeard (Nick Offerman), and Unikitty (Alison Brie). Bricksville becomes a chaotic Apocalpyseburg. When General Mayhem (Stephanie Beatriz) arrives, she’s ordered to bring five of them back to the Systar System for the candy-colored wedding of shapeshifting Queen Watevra Wa’Nabi (Tiffany Haddish). So Emmet sets off on a rescue mission, aided by Rex Dangervest (also Pratt), to find his kidnapped friends. The amusing voice cameos include Jason Momoa as Aquaman, Channing Tatum as Superman, Jonah Hill as Green Lantern, Cobie Smulders as Wonder Woman, and Supreme Court Justice Ruth Bader Ginsburg and Bruce Willis as themselves. Director Mike Mitchell continues the slapstick/visual gags/pop-culture concept of the original film, but despite the plasticky shine, not everything is awesome in this lesser sequel. Optional. [Note: DVD/Blu-ray extras include audio commentary (by director Mike Mitchell, writers/producers Phil Lord and Christopher Miller, and animation director Trisha Gum), outtakes and deleted scenes (12 min.), the production featurette “They Come in Pieces” (9 min.), an “Emmet’s Holiday Party” short (3 min.), the music video “Super Cool” by Beck featuring Robyn and The Lonely Island (3 min.), and LEGO promo pieces. Exclusive to the Blu-ray release are bonus DVD and digital copies of the film. Bottom line: a fine extras package for a so-so sequel.] (S. Granger)
