It was not the worst Sony-marvel movie. It would be much better if they didn’t create the stupid Kraven is a super-lion-blood/witch-magic superhero back story. Also the movie seems like they needed less or better characters, I think the brother and one of the villains should have been excluded from the film entirely.
Comic book Kraven had powers on par with Black Panther, from drinking the Calypso Serum that was retconned to be made from the heart-shaped herb. I haven’t seen it yet, but they probably changed it to avoid using anything Disney owns.
