“Unbreak My Heart” (**1/2 out of four) was a hit-and-miss biography of R & B singer Toni Braxton (Lex Scott Davis) who became a worldwide phenomenon in the ’90’s but saw her career encapsulated by financial and health problems before she returned to her family roots and made a comeback. Early scenes showing her upbringing seem artificial and staged but movie succeeds best in its second half showing her health issues and financial decline. Davis looks more like Beyonce or Ciara than Toni Braxton but her sincere performance keeps this afloat and makes this worth watching. The real Toni Braxton makes a cameo in the final scene.
