Instead of a sweet, 13-year-old white boy waking to find himself in his 30-something body, writer/director Tina Gordon's lighthearted take on Big gives us a rude, 30-something black woman waking to find herself reverted to her gawky 13-year-old frame. In other words, Little is about as familiar-yet-slightly-different as high-concept Hollywood offerings get. With its leads portrayed by Regina Hall, Issa Rae, and the remarkable Marsai Martin, it's also about as enjoyable as they get – though you can't help wishing there were even more here to enjoy.
