I may have interpreted the movie wrong, but I think the movie is about setting up that conflict. The whole movie revolves around Miles not being a “true” Spiderman, an error. My understanding is that the trilogy is more about taking destiny into your own hands and showing the “spider-verse” assumptions are wrong. If true it plays nicely with the fanbase feuding about whether Peter Parker is the only “true” Spiderman, or if anyone can truly take up the mantle.

Now, miles dad usually does die, so maybe not exactly, but my takeaway from the movie was to not allow others to tell you what you should/shouldn’t be/do.
