"Nang Sib Song" is sad and i think it sadder den "Bla Boo Tong" . I feel sympathetic for the 12 Girls , the Giant Lady & the two lover since it end in tragic and in "Bla Boo Tong" it actually a happy ending but the story of the mom & child hood was a tear jerker. "Keo na ma" is another sad boran though it a comedy too but toward the end you have to feel sympathetic for Keo when her son die and when she trade her soul for their son life.
