Tokyo Godfathers (2003)

Three homeless companions finding an abandoned baby might sound like a device for instant sentiment. Satoshi Kon instead lets their arguments, old wounds and wildly different instincts complicate the rescue. Their makeshift household already has a history; caring for somebody new exposes how much they owe one another. The animation is exuberant and the coincidences deliberately extravagant, with hardship and prejudice present rather than tidied away.
