Woman screws up entire city; her man has to fix it.
Much as I like Del Toro, this is a really bad knockoff of the aliens franchise that lacks any intelligence or even common sense. Mira Sorvino is fine but unlike Ripley her character is hapless and irresponsible. She 'saves' Manhattan by creating a potentially even bigger problem (proving maternal instincts) and the only reason it doesn't escalate from there is that men sacrifice themselves to make it right. Her husband/fiance/whatever somehow isn't consumed in the flames of her ineptitude but does manage to fix what she broke. Not exactly the feminist image Ripley embodied, for instance.
"I'll book you. I'll book you on something. I'll find something in the book to book you on."
