Well fans are fans because they like everything their fav does. That you find each act of hers applaudable isn't something I should hold against you, so in fans' opinion the act may be stunning.
Those who aren't hard core fans but genuinely like her would like to look for the positive aspects of her act. Those who don't give a shit about her won't give a shit about the act and those who dislike her would want to find it offensively bad. 😆
Honestly in my opinion there was little to no dancing on Sanaya's part and this is where she lost marks. Whatever little dance was there was by Jai on the floor. Apart from a couple of acrobatic moves, all Sanaya did was swinging over a harness.
I hadn't found their previous aerial act all that glorious as it was made out to be because the dance on the floor was messy even in that one but the aerial was still visually pleasing. Unfortunately it wasn't the case here. Sanaya and Jai appeared uncomfortable. It was a nice attempt but did not turn out to be what a finale act should have looked like.
