If she would've put anything about Corey in the video ya'll would've attacked her for using his death to promote her music.
If she would've had actors playing out his death everyone would've thought she was using pity to sell.
I love the video, the meaning behind it. The dark room represents the loneliness inside her and as the light breaks through its her coming back to life, and finally uplifting herself. I thought it was very artistic, emotional and beautiful. I'm glad it didn't scream sadness but rather enlightening.
