A dark comedy about alcoholism, male entitlement, and kaiju.
Gloria (Anne Hathaway) is a mess. She hasn't worked in a year. She's living in an alochol-and-hangover-induced haze, barely functional, lying her ass off to everyone - especially her boyfriend (a very plummy and condescending Dan Stevens). When he dumps her, she crawls back home to her parents' old house (which they still own but aren't living at) - ostensibly to get better, but really just to hide.
While walking home, she meets an old friend from childhood, Oscar (Jason Sudeikis), now a bar owner who clearly has long had feelings for Gloria. He gives her a job as a waitress, and she falls into a comfortably numb routine of working there in the evenings, and drinking the rest of nights away with him and his buddies (Tim Blake Nelson and Austin Stowell).
Except right then, a giant monster starts attacking Seoul. It materializes out of thin air, stomps through the city, and then vanishes, leaving destruction in its wake. And Gloria starts to notice things - it appears whenever she tromps through a particular park outside her old school, it doesn't seem to acknowledge the areas around it like it can even see them... and it mimics her exact gestures. Somehow, improbably, Gloria is causing this monster to manifest. And so her quest to clean up gains new urgency. But it won't be easy - and not everyone she's surrounded herself with will be an ally, and she's not the only one with monsters to deal with.
Nacho Vigolando's script is sharpest when it comes to its two main characters, imbuing them with genuine depth, pathos, and humor. The origin story it presents for how this is happening is a bit too literal, but otherwise the monster action as presented is very clever. Using the park as a stand-in for Seoul is particularly effective in a couple of later scenes.
Above all else, this is a triumph of performances. Sudeikis is a revelation - all entitled nice guy masculinity slowly seeping into possessiveness, jealousy, and misanthrophy. He takes a big leap to some dark places with this one, and he nails it - especially because, in a traditional rom-com, his character would obviously be the sweet "guy she left behind". Here, though, Sudeikis and Vigolando dig deep and find something much uglier under the skin. Stevens and Nelson play strong support, though Stowell is underdeveloped (especially given his role in igniting some of the plot turns). He's just a nice, dopey, hot young guy - which serves the plot enough, but maybe could've used some meat on the bones.
As for Hathaway, this is probably her best performances in, frankly, years. She has a real gift for finding the comedy and melancholy in her character's self-destructive tendencies, making Gloria sympathetic while not shying away from the fact that she's a completely irresponsible trainwreck. She gets at exactly how hard it is to be better, how much of a daily struggle it is (though there is a bit of a skipped beat at one point as she suddenly gets a lot more cleaned-up, but given what's come before that it's understandable that Gloria would very rapidly try to dry out).
Ultimately, it's a very fresh, funny and thoughtful take on monster movies and rom-coms. Definitely worth checking out.
