About
You’ll likely enjoy this if you want a super-silly, warmhearted 80s sci-fi rom-com with broad humor and a bit of nostalgia, like Space Jam’s playful vibe; Not for you if you dislike dated gags or lowbrow jokes.
Pros: goofy 80s charm; sweet fish-out-of-water laughs; fun romantic energy | Cons: thin story; dated jokes and effects; runs a bit long
