I love Love Me Back (album version), it's such a b-movie type of PV that it becomes entertaining. I love the looks, the dancing, the only part I dislike is the love interest (both men are not that attractive, you can't always win).
I don't mind the shift from her over the top ero-kakkoi to what we get nowadays, because people nowadays see overly sexy things, specially for someone her age (she's not old at all, but we all know how society and pop acts are seen when they are over 35...), as trying too hard or something like that. For example, I love PCD and their new single REACT is a bop, but I can't see Kumi dancing and doing poses like this...
... which is something she basically did back in the day. I'm all in for women expressing their "sexyness" and all, but I don't think this is what Kumi wants right now.
We all know this isn't the '00 anymore, sex doesn't sell as it did back in the day, if we go to a more "please the audience" route.
It's not that long since SO FEVER, and that's was such a throwback to her ero-kakkoi days.
