Opinion: Jennifer Lopez's "Halftime," story is not what it seems.

To be a star for more than a decade, it takes a very special personality. Either you have to be a chameleon, 

Lady Gaga or Madonna or a diamond. It is a shiny, indestructible, and unbreakable diamond that will not be destroyed no matter what happens.

Jennifer Lopez is the stunning, unnervingly constant centerpiece of Netflix's new documentary "Halftime 

She is a diamond. Although she has been doing this for some while, the movie keeps reminding us that  

she is still the same 27-year old Lopez who was the star of 's breakout hit, "Selena," in 1997.  

As "Halftime," opens, we see her blowing out the candles from her 50th birthday cake.

As "Halftime", however, shows, there is a difference between being a performer, artist or person and being a documentary subject. 

Lopez, a woman working in the entertainment business, lives under intense scrutiny, especially as a woman of colour. 

Although the protective armor she has built for herself and her forensic control over her story are understandable tools for survival, 

they don't seem to be able to help but undermine the success story of "Halftime."
