Like a Korean Wes Anderson film. That thought didn't occur to me until one of the final (well-composed) shots but now I can't unthink it.
Fun visuals, fun characters, fun editing, fun dialog, fun setting. This was by no means a perfect film but I didn't stop smiling once so I'd have trouble faulting it.
Most of the characters are absolute caricatures of mental illness but I still loved the way it was handled and how bizarre the whole thing felt. The way the doctors were all the crazy ones, and the patients just needed different socks so they could fly away in the night time.
