A straightforward take on BPD from Hollywood?

The CW show "Crazy Ex-girlfriend" follows the life of Rebecca, a woman who moves from New York to LA to pursue a relationship with someone she dated briefly in high school. As the show progresses, she ends up being diagnosed with BPD. Follow the link for inside view from Elle on how the show came to use the diagnosis. I'd be curious to hear others' take on this, from anyone who has seen the show?
