[Utena]

Well, first, Be Strong's purpose is not to be creative, it's to SELL. It's an album promo track afterall, I wouldn't expect anything but what's made her popular to begin with.
Other tracks from this era were different though (SAKURA, I LOVE YOU? & GO FOT IT!! mainly). Obviously, it's hard to please everyone, but at least she's trying different things, yet keeping in mind what a more mainstream part of the population would like.
I find it a bit odd if not harsh to call her boring when she's only been trying to offer us some variety while keeping some sort of unity in style... You might not like it, but it's not what I would call being boring. Esp. when she has not been around for so long...

I can only speak for myself, but I enjoyed Tatoe Donna Ni.. & SAKURA ILY a lot, I still listen to those two a lot. On the other hand, not too fond of Watashitachi & GO FOR IT!!.. I used to like every single song Kana released, but this time I can't say I was pleased.. Even with the b-sides :/
