Spider-Man movies by fixing some of their biggest flaws.
Although The Amazing Spider-Man movies have another chance to succeed is the MCU's reinterpretation of Electro.
The Amazing Spider-Man 2 failed its main villain. Electro's design, despite not following the character's original look, was visually striking; his accompanying score was top-notch, and the talented Jamie Foxx was a great choice for the role. However, the movie focused so much on setting up an extended franchise that not one single part of its story received its fair amount of attention. With so many elements fighting for screentime, Max Dillon's transformation into Electro was reduced to falling into a conveniently-placed vat filled with eels while fixing some electrical equipment at Oscorp. Besides unconvincing, Electro's origin story felt like it belonged in a movie like Batman & Robin rather than the MCU or Sam Raimi's trilogy.
Jamie Foxx has already confirmed that the MCU's reinvention of Electro "won't be blue in this one," which is a good first sign. A change in appearance suggests a change in origin story. This could benefit any other character traveling through the multiverse, as their reintroduction in the MCU can fix any major flaw that couldn't be corrected otherwise. On the other hand, well-received characters like Evan Peters' Quicksilver can replace their less-celebrated MCU counterparts. Although unfortunate for those few who liked some aspects of the soon-to-be-forgotten characters, the bright side of the MCU's ability to substitute any character is that almost everyone has a second chance to reach their full potential.
Sony's The Amazing Spider-Man 2 forced all of Spider-Man's villains to be related to Oscorp, which subsequently limited their origin stories and motivations. With a well-developed Electro in Spider-Man: Homecoming 3 as the first significant replacement, there's little external content the MCU can't fix and integrate, including Spider-Man 3, and even Deadpool, whose incorporation into the MCU is still a mystery.
