BOOGY FEVER!!!
Just kidding!
But, seriously, she's just standing there doing random crap. She's big and powerful, which makes her prideful and arrogant. That's a cliché but classic villan element. But this? She's just fighting with no finesse or thought.
She was a dinkey little princess who got a bunch of power in a cheap and apocalyptic stunt. She isn't a shinobi--she never trained, she never truly fought, she never earned her powers. She's from a time where her enemies didn't have the kind of power Naruto or Sasuke have now.
I liked Madara at first when he was actually going toe to toe with the shinobi and fighting with more finesse. But he became more and more powerful, therefore transforming from a perfect, finely homed scalpel to giant flaming meat hammer. Kaguya!? She's an explosive 20 ton pile of crap. Move out of the way and you're fine--no thought behind it. Sling power around until you hit something! Until then, just talk, gloat and make creepy plant babies.
