The Justice League faces a challenge unlike any before in _JLA Adventures: Trapped in Time_. In the far distant future two Justice League candidates, Dawnstar and Karate Kid, accidentally release a frozen Lex Luthor; who in turn frees a dangerous villain known as the Time Trapper and travels back in time with a plan to prevent Superman from growing up on Earth and forming the Justice League. The film makes good use of the Legion and League characters, including a lot of fan favorites (Wonder Woman, Cyborg, Bizarro, Toy Maker, etc.). Also, the voice work is well-done and the art is really crisp and vibrant. However, the time travel plot is pretty standard, following the usual tropes and clichés. Still, _JLA Adventures: Trapped in Time_ is an action-packed and entertaining superhero adventure.
