I think Simone is still trying to find a balance between her voice, and the voice Perez created for Diana. She's operating within all the more recent stuff, but seems to mostly be looking at Perez's run for how to write Diana and her world, and that's a very different tone from what she usually writes. Hopefully, she'll settle in soon. Even if she doesn't, it's far better than the books has been in ages and ages.
