Frieza's return works because the movie earns the revenge fantasy through pure spectacle and lets Goku and Vegeta's pride do the actual storytelling. The fights move at a speed most anime can't sustain, and the theater crowd energy during Vegeta's rage transformation is something you feel in your chest. It's a straightforward revenge plot with nothing new to say, but it says it loud enough that you don't care.
Frieza's former lieutenants Sorbet and Tagoma have waited years for this moment. They scour Earth hunting for the Dragon Balls, driven by loyalty to a master most thought long dead. When they finally gather all seven orbs, they speak the wish that will change everything: bring back Frieza. The galactic tyrant returns to life consumed by rage. Decades have passed since his defeat at the hands of the Saiyans, and he burns to settle that ancient score. With newfound power and an army at his back, Frieza sets his sights on Earth, where his sworn enemies now live in peace. Goku and Vegeta must face a vengeful god intent on annihilation. But this isn't the same Frieza they once knew. He's trained, he's hungrier, and he's brought reinforcements. The Saiyans will need to tap into reserves they've never accessed before to stop him. This is about legacy, power, and the terrible weight of leaving enemies alive.
