Questions about Molly Long....

Sorry in advance if this counts as off-topic, but I hear a lot of discussion about the choreographer Molly Long related to this show. I believe she choreographed "Girlz Night Out", "Stomp the Yard", and "Moulin Rouge", and I read online that she did some choreo for Raising Asia as well. I know she's a really big name in the American competitive dance scene, and I've seen her choreography go viral a few years ago with that Pop Music dance that everyone was doing.

I've seen both praise and criticism of her choreography on this sub, and I don't know where I stand quite yet on her work as a whole. I think Stomp the Yard is a bit overrated, I like Girlz Night Out well enough, and I do not like Moulin Rouge. However, when I see some of her choreo, I wonder why she didn't try to lean into that a little more with the girls on Dance Moms? Like the super tight isolations and tiny synchronized movements that go with accents in the music, that kind of thing. I know that some of the girls might have struggled with that, and also that trying to work Mackenzie into the numbers being a drastically different height may have limited her creatively. But I think it would have been good for her to try to get the girls working in tighter synchronization, which is something they sometimes struggled with in season 5.

Am I wrong? Could the Dance Moms girls not have handled it? Do you think production limited what she was allowed to do? Is there anything about Molly Long I'm overlooking? I've heard she's done some inappropriate pieces, but I haven't gone out of my way to seek them out. Are they Abby-level bad?
