HOME ALONE: Poor little Korean kids. In So Yong Kim's Treeless Mountain, two sisters (Jin, 6, and Bin, 4) must take care of each other after their mother leaves them to search for their estranged father. Parents of the Year all up in this piece! In this semi-autobiographical tale (whuuuuuuut?), things move slowly and tenderly while the children are left to their own devices and struggle to adapt to the new status quo. Treeless Mountain plays twice a night at the NWFF through Thursday. 7 p.m., 9 p.m. // Northwest Film Forum // 1515 12th Ave. // $9 more ›
