Selfish Kumiko
Kumiko was SO selfish. She screwed so many people over - Like her boss, for example (which I can almost forgive because he was terrible) but I'm mostly talking about the cab driver and hotel employee in particular. I was rooting for her at first since I know what it's like to be depressed and a master of self-sabotage but god, it was so hard to wish her well when she didn't seem to care about anyone but herself. Nobody she ran into on her journey deserved what she did to them.
One of my least favorite protagonists in a film in a while, though I will say that Rinko Kikuchi was amazing. Such an excellent performance.
There's nothing the least bit funny about stealing a meal from Neal McBeal the Navy SEAL.
