Animated origin story for the siblings of the title (voices of Chris Pratt and Charlie Day) dutifully accounts for various elements in the landmark video games in which they are featured. Magically transported to an alternate universe, the duo of Brooklyn plumbers become separated in the process, one landing in an upbeat realm ruled by a fetching princess (voice of Anya Taylor-Joy), the other in the dark domain of an evil turtle (voice of Jack Black) who is not only scheming to conquer the happier territory but to marry its sovereign as well. The occasional touch of humor and clever use of music aside, co-directors Aaron Horvath and Michael Jelenic's adaptation amounts to little more than a frantic series of chases and showdowns. While free of any genuinely objectionable elements, the instantly forgettable proceedings might frighten little ones. Much stylized violence, including explosions and brawls, characters in peril. Spanish language and titles options. The OSV News classification is A-II -- adults and adolescents. The Motion Picture Association rating is PG – parental guidance suggested. Some material may not be suitable for children. (Studio Distribution Services; also available on Blu-ray)
