Honestly, watching her in interviews and anything she really seems to light up the most when talking about her family and her work. I really think she is passionate about what she does, she's just having so many personal issues that I think it naturally just shows even when she's performing. I definitely think she needed more time off before her "comeback" to recoup and take care of herself. I have always loved her and been a huge fan and as excited as I was to see her on tour twice and her albums and music videos, I would rather her take care of herself and then come back when she can be in it 100%.
I think the video's ok, not great. Britney looks good (and I love all her shoes!) but it's so minimalist, her videos are usually so complicated and have at least 8 crazy outfits, hair changes, etc I like all that stuff. And I don't think it fits the song at all really
