You didn’t ask me, but I’m a big Kate Bush fan, but mainly of her 80s work. That first album The Kick Inside (I didn’t care all that much for the follow-up Lionheart) and then the later albums like Never for Ever, The Dreaming, The Hounds of Love and The Sensual World are all pop masterpieces, IMHO. Things start to decline with The Red Shoes and so many people loved Ariel her first album after a long hiatus where she raised her son, but for me, the magic was gone at this point.
I bought many of her albums back in the '90's. For some reason or another I passed on her first album (think that it was because I already had a number of the songs on it on The Whole Story?) and also passed on The Lionheart (due to comments from friends).
Like you, and I'm sure a number of others here, I have and love her other albums. Red Shoes is probably my least played album of hers and the last one that I purchased. Aerial is currently on loan from a friend. Had meant to listen again to the second disc from that album last night, but that didn't happen. Yes, it's rather lower-keyed than her earlier albums, but people grow and change, mature, have relationships and sometimes kids too. I think that the first time that I listened to it, in my mind, I was comparing it to her earlier albums which were very theatrical and more--how do I put it--more in your face(?)...out there(?). This is still in her own unique style, but quieter, maybe a bit more reflective and with the added perspective of eyes and a heart and brain that have seen and experienced much more and thusly have more to share.
I've been haunted by her ever since I first heard her and saw her incredible videos. It's like she came from another planet.
That's one way to put it.

I haven't ever seen her videos/shows alas, but have seen a few pictures of them. I received the impression that they were quite the production--very theatrical. She has a great way of creating all of these wonderful characters and stories!
