A couple clarifications because my first post sounds a bit too negative:

I enjoyed Alita a lot too, but Solty Rei is that reminescent of it. It's really too early to say anything negative or that positive about it, but I just included those others as a basis of comparison. I only dislike the elements that reminded me of DearS and BakuTen, because I hate those shows, even though I watched them the whole way through.

If you liked BAA, you'll probably like Solty Rei.
