Jennifer Lopez is an icon. There’s a reason she’s managed to captivate audiences for years. You can argue it’s the mixture of her talent, charisma, and hustle. She understood the game and what it takes to become mainstream in the US, especially as a Latina. But not everyone agrees that she deserves to be where she is today or even that she deserves more acknowledgments, recognitions, and awards. That’s, in fact, the main idea behind her new Netflix documentary, “Halftime.” It’s all about how regardless of how hard Lopez has worked these past few decades, she still doesn’t seem to get the credit she’s due.
