I agree with you. I don't like the fact Mephisto is becoming so deeply ingrained into the overall Spider-Man narrative. Spider-Man has typically been about science and science fiction, not magic. The Totem crap was the first time magic was inserted into the mythos and Peter became a type of "chosen one" (the laziest of all superhero tropes, IMO), a development I hated at the time (along with organic webbing and the "Other" lol). I'd prefer if Peter wasn't born great or destined to become great, rather he became great through struggle and learning from his mistakes, aka his classic character status quo.
