Is this Sony trying to maintain its claim to whatever portion of the Marvel IP it still has left?
My understanding it is exactly this. Sony has to make a “Spider-Man” movie every X years or the rights revert to Marvel (which would now be Disney).“Spider-Man” includes the hero and all his rogue’s gallery. So, we had Spider-Man, and Spider-Man reboot. Then when they figured we couldn’t take another reboot they started on Venom and Morbius and now Kraven. Apparently, they don’t care if the movies are any good, or even whether they break even. Like that Fantastic Four movie made by Roger Cormin just to keep the rights.
