Singaporean writer-director-thesp Jack Neo capitalizes on the success of his 2002 laffer, and its spin-off tube series, with “I Not Stupid Too” an overdue — and overlong — sequel. Proselytizing pic favors child protags over insular and stubborn adults, but loses its comedic rhythm as it rams each lesson home. Like its predecessor, pic did terrific local biz when released in January. The first entry had some charm that seduced other territories, but sequel’s overwhelming preachiness will hinder its ability to prevail elsewhere.
Unrelated to previous yarn except thematically, sequel introduces Jerry (newcomer Ashley Leong), an 8-year-old whose learning difficulties partially stem from his inability to get the attention of his middle-class parents (Neo, Xiang Yun). While Jerry struggles to invite his bickering mom and dad to his school play, working-class teen Cheng Cai (Joshua Ang, one of several child thesps from “I Not Stupid”) falls in with a street gang after experiencing more violent parental difficulties. Ongoing hectoring about loving children is well-intentioned, but a push toward serious drama is unconvincing. Perfs have an endearing quality and tech credits do the job.
