A story about two broken people both running from their current realities due to shitty dads. What's with dads just abandoning their kids when they get divorced? That's weird. Don't do that, dads.
Koji Ookura is a walking cartoon, and he basically makes the movie. There's a lot of tension throughout the movie of whether or not he's actually a creep or just misunderstood, so when he does actually end up attempting to rape the protagonist, it's kind of a bummer (I mean, not just because rape's a bummer) but because you want to like him in spite of his faults and he was acting as a stand in father figure for Hachiko. Turns out he's actually just terrible, no matter how sympathetic the film tries to paint him.
