The big concept within Nacho Vigalondo’s Colossal is clever enough that the movie might’ve rested on it alone. I mean, I can’t remember the last time I saw a film about a woman who steps into a kiddie park in her hometown and causes a giant reptilian monster to emerge in South Korea. So it’s got that going for it. But once Colossal sets its conceptual hook, it pushes its zany premise into authentically uncomfortable territory. It’s actually about something.
The woman in question is Gloria (Anne Hathaway), a frazzled millennial at loose ends. Scolded by her boyfriend (Dan Stevens) about her incorrigible partying, she moves out of their New York apartment and back to her parents’ house in a town upstate.
