When Earth astronaut Capt. Chuck Baker arrives on Planet 51 -- a world reminiscent of American suburbia circa 1950 -- he tries to avoid capture, recover his spaceship and make it home safely, all with the help of an empathetic little green being.
Planet 51 has a clever premise—inverting the alien-invasion trope by making the human the outsider on an alien planet modeled after 1950s Americana—but squanders it with a formulaic fish-out-of-water narrative and thin characterization. The voice cast is serviceable but unremarkable, with little nuance or memorable performance work. Visually the animation is competent and colorful for its era, capturing the retro aesthetic reasonably well, though it never pushes boundaries. The concept itself earns modest novelty points for its role-reversal idea, even if execution is pedestrian. The ending is predictable and rushed, offering little emotional payoff beyond a tidy resolution.
