💥 Planet 51 Reviews
Personal Review
Okay, so ‘Planet 51′ isn’t winning any awards for originality, but I still found it charming. The whole ’50s Americana meets alien invasion’ concept was fun, and Rover the robot totally stole the show! I especially loved the little nods to classic sci-fi movies – kept me entertained even when the story got a little predictable. It’s a lighthearted, feel-good movie, perfect for a family night in with pizza.

Professional Reviews
- Rotten Tomatoes: “While visually appealing with a clever premise, Planet 51 suffers from uninspired writing and a reliance on tired sci-fi tropes, failing to fully capitalize on its unique role-reversal concept.
- Common Sense Media: “This animated film flips the alien invasion story, but it’s only mildly amusing. While the animation is colorful and engaging, the plot relies heavily on clichés and the humor is often juvenile, making it a decent but not outstanding family movie.
- IMDB: “While the characters are endearing, the film’s strength lies in its imaginative world-building and numerous nods to classic sci-fi. Though the plot may feel familiar, the animation and voice acting provide an enjoyable viewing experience for families.
