Directors Pablo Biglang-awa and Veronica Velasco (who also penned the screenplay) create a simple film brimming with heart sans the cheese fest. With a quiet and tell-it-like-it-is approach, Inang Yaya relies more on a charming and low-key story as its foremost strength. It took all the cliches, wrapped them in an old diaper and tossed them out the window. Some people may find Inang Yaya boring--the characters mostly talk while sitting around--and might find pleasure in a few product placements, including Taheebo Herbal Tea and Blue Bay Tuna.
Performances are top-notch all around for the principal cast. As nanny Norma, Marical Soriano was very effective, a shoo-in for next year's awards derby. But I miss her pitch-perfect histrionics, her crying buckets as she slides against a door to the floor. Now if there's anyone in the film who really deserves a nom, that would be Liza Lorena as the snarky grandmother. Even when she reveals her tender and compassionate side, she's still snarky. You don't get performance gems like that everyday.
As a side note, the Inang Yaya page on IMDb.com says "If you like this title, we recommend... Antipolo Massacre (1993).
