19 & Dangerous received generally favorable reviews from music critics. In a review for New Musical Express, Sophie Williams characterized the album as "a collection of uber-confident, and sensational afropop gems". A writer for Pulse Nigeria, described the album "In a way, ‘19 and Dangerous’ is like the love-child of Adele's ‘19’ and Rihanna's Good Girl Gone Bad, underpinned by the fiery, alluringly vain, carefree, consequences-be-damned Gen Z tendencies of ‘Cast,’ the album opener - or manifesto. Interestingly, Rihanna was 19 when that album was released and Ayra Starr is a card-carrying member of Rihanna's navy". Rating the album 7.9/10.
