Personally, yes. I kinda liked her.

She kinda came from nothing and she is basically she-Thanos from Avengers Endgame, but I liked her story, look, voice acting, powers, moveset, etc.

She is defeated TWICE in the same game like Shao Kahn and Shinnok before her, so I'd argue all final bosses were "weak" in terms of power level and lore. But at least she is interesting. She just doesn't want to conquer and destroy and submit, she has a vision and just wants that vision to come through and stay still. She thinks that in doing so she will keep the universe in balance and precvent a far worse threath, but I like to think of her as an apprensive mother who wants both her sons at the top of the food chain.

She needed to use her legs in combat and not hover.

MK1 Shang Tsung...

If you count morphs/summons, T-Wrecks uses it's legs to trample our asses.

Ka-Tra

MKMSZ Shinnok levitates too.

Comes down to the outfits (exposing lower legs to kick) but Ermac in MKX floats and still uses kicks. Sindel in MK3 as well, differently.

We already knew very little about the Elder Gods, and now there's a higher Goddess. Personally I would have made Kronika an Elder God who persuades the rest into changing the sands of time. That would have made an opportunity to explore the Elder Gods and know more about them. In appearance and personality, she's exactly the opposite of Shao Kahn, witch is logical in times like these that they made her like that.

Some say powerful people come from powerful places (when it comes to MK).
