Setting Into the Spider-Verse aside, I think Sony has done a poor job with Spider-Man over the last decade. And Sony knows it, its why they inked the deal with Disney/Marvel in the first place.
As for Homecoming not breaking new ground, well that is to be expected. We've seen the origin story of Spidey now several times. So when they forewent retelling a lot of elements of his origin story I thought it was good. We don't need a recap of those things, like Uncle Ben dying and such. But it was a story that needed to be told to get the character established and differentiate it from the other two series. Far From Home will be the telling factor on if a Marvel produced Spidey film breaks any new ground or not.
Had Marvel (Disney) had the rights to begin with there is no telling what kind of story we'd get. And no telling if we'd be on a third reboot of the character or not, I'd like to think not. When you have the properties in the hands of the creators they tend to do better with it than some other company.
The only reason why I think Into the Spider-Verse was any good is because Avi was producing. As former head of Marvel (pre-Disney) he has a love for the characters that others wouldn't. Had it been in the hands of another, maybe it wouldn't have looked and felt like a comic book come to life. So thank Avi, not Sony for Into the Spider-Verse.
