There's a lot going on in this strange, perplexing but still intriguing film by director Nacho Vigalondo.
The always-engaging Anne Hathaway (she of the good looks and the impish eyes) plays Gloria - an alcoholic whose behaviour has tested her boyfriend Tim's patience too far (Dan Stevens - he of the fluttering hearts that kept the first seasons of Downton Abbey firmly in the ratings).
When Gloria loses her job and Tim kicks her out of their New York apartment, Gloria is forced to move back to her small home town. There she reconnects with her childhood buddy Oscar (Jason Sudeikis - mainstream comedy's nice guy with a bit of a bad-boy streak) who gives her a job in his bar. This, obviously, is not good for her alcohol problem but seemingly good for her social status.
All seems well as Gloria spends her days serving drunks and her evenings becoming one in the company of good 'ole friends she hasn't had time to reconnect with.
And then … well … let me try my best to explain this: a Godzilla-style monster wreaks havoc on Seoul in South Korea. It turns out that somehow, this monster is connected to Gloria - her inner personal demons writ large perhaps.
When another monster appears to cause more trouble for the South Koreans than an early morning Kim Jung-un missile strike, it turns out that monster No 2 is somehow connected to Oscar. While some addicts may have to deal with metaphorical monkeys on their backs, these two have to negotiate literal city-destroying hundred-foot monsters on theirs.
