The song “Big Unknown” which plays over the credit of “Widows” with director Steve McQueen’s starring Viola Davis gave the movie its essence according to critics. Her initial “Flower Of The Universe” movie original soundtrack song gave illumination to the movie. According to Stereogum online magazine, director Ava DuVernay personally requested a Sade’s song for her adaptation of “A Wrinkle In Time”, which featured TV show host Opera.
According to DuVernay “Personally, I thought “The Flower Of The Universe” was only OK. “The Big Unknown,” on the other hand, is a song that puts Sade’s myriad imitators to shame — a minor-key ballad that manages to land some heavy emotional blows despite its impeccably tasteful lite production. “Only love could bring us to this bitter plane,” Adu sings. “And only one of us who’s gonna walk away/ Here in the deep below/ That only darkness really knows/ I’m hoping for a humble seed to grow.”
