Loud, trashy, sweet and weird, the Mighty Morphin Power Rangers reboot “Power Rangers” is not merely an ideal film for rambunctious and undemanding 12-year olds, it actually sees the world through their eyes. In theory, the heroes are high school students. But they’re actually a Disney Channel-styled fantasy of the splendors that await kids when they finally become full-fledged teenagers and can Do Whatever They Want. These heroes are misfits. They gather in detention in their high school, a scenario that promises to turn into “The Mighty Morphin Breakfast Club Rangers.” Lo and behold, that’s what you get: a mix of shenanigans, heart-to-heart talks and widescreen punch-outs between monster battles.
