The Transformers continue to roll out, and so soon after the entertaining “Transformers: Rise of the Beasts,” released in 2023. The live-action path for the franchise has been put on temporary hold, with “Transformers One” returning the saga to an animated realm, presenting a feature-length adventure that’s the first cartoon offering for the robots in disguise since 1986’s “Transformers: The Movie.” Traumatic events are lightened a bit for the new effort, with screenwriters Eric Pearson, Andrew Barrer, and Gabriel Ferrari out to established a fresh frontier for the characters by dipping into their pasts. “Transformers One” is a prequel of sorts, offering a chance to get to know battling robots Optimus Prime and Megatron before they were mortal enemies, offering a lighter side to the violent war, or at least a glimmer of hope as darkness arrives. Director Josh Cooley (“Toy Story 4”) is a little unsteady when juggling silliness and solemnity, but he scores with adventure, delivering appealing artistry and some operatic turns of plot as the characters return to their colorful, smash-em origins.
