You can't just slot any established character into any role and expect it to work. Rhino has (basically) never been a conniving, evil mastermind, so portraying him as such in "Kraven" could be a big misstep. He isn't such a precious character that changing him is unthinkable, but there are simply better villains for that role who could have been used instead.

The most interesting Rhino arcs in the comics deal directly with his status as a villain of the week. The 2001 story "Flowers for Rhino," for instance, sees the big guy modify his brain to become a genius criminal after getting sick of being treated like a dumb henchman. He achieves incredible things after undergoing the transformation, but his underworld success doesn't make him happy. In the end, he learns to embrace his true self and returns to being the Rhino we know and love.

Sony doesn't need to do that story, but it's a good example of how you can make a character more important without abandoning the traits that make them unique in the first place. If the MCU has succeeded at one thing, it's meeting zany comic book characters right where they are and building around them. Sony hasn't quite figured that lesson out yet, which might be why "Morbius" feels more like an early 2000s adaptation than a modern comic book blockbuster.

A trailer is just a trailer, so things could turn out a lot different from how they look right now, but it seems that "Kraven the Hunter" is once again falling short with its version of Rhino.
