zack snyder is releasing his recut, reshot, $30m+ directors cut version of Justice League sometime in 2021 so I'd just wait for that, its gonna be an epic disaster or an amazing movie, who knows
re: 2 wishes, its goofy but basically Cheetah gets Diana-equivalent powers with her original stone wish. She tells Pedro she wants to be an apex predator, she doesn't actually get that wish fulfilled by Deus Ex Wish but instead Mando sucks wishpower(tm) from randos during his telethon power up and grants them to Cheetah. He mumbles about "give her more power" a few times while also wishing himself better organs, health, etc. Its all goofy as fuck and doesn't make any sense, so not worth thinking about too much. There are a million little things like that they try to paper=mache over plot holes, like a helicopter is behind Pedro when he returns to his son to explain how he traveled from Telethon Island back to the white house but each sad attempt creates 10 new plot holes (how did the son get to the WH, why would the pilots listen to Mando if he is de-wish-powered, etc)
also as an "apex predator" she should have turned into a Crocodile, T-Rex, Shark, Bear, etc. not a fucking cheetah lol. actually the ultimate apex predator on Earth is a dude with a gun
