If you listen to my podcast, you'd know that Pat and I are very excited about the inclusion of Spider-Man within the Marvel Cinematic Universe. In one episode, we explain that, ideally, we'd like to see Peter Parker as Spider-Man in his first MCU appearance: Captain America: Civil War. However, we'd prefer to see Miles Morales as Spider-Man from then on. We were hoping Civil War could be used as the transition point from Peter to Miles. It could be a powerful swan song for the cinematic Peter Parker as well as a "passing the torch" moment for Miles Morales.
We've heard rumors that two actors are currently under consideration for Spider-Man, and I've confirmed that both of those rumored actors are white. It's obvious to me that these actors would be playing Peter Parker.
However, the current rumor from reporter Jeff Sneider is that Spider-Man will be "non-white," specifically black or hispanic. This would easily fit a description of Miles Morales, who is of both black and hispanic descent. This leaves Peter Parker out of the MCU entirely. Sneider also states that the previous casting rumors are incorrect.
So, while it's sad that Peter Parker is done on the big screen for now, I would be quite happy to see Miles Morales get his time in the spotlight. As a long-time fan of Spider-Man in all his incarnations, I'm very much okay with Marvel taking a chance on a lesser known character while adding some much needed diversity to their lead roster.
My desire to see Peter Parker pass the torch was not for my benefit, but for the benefit of the casual moviegoer. I assume that most Spider-Fans who have only seen the movies might be confused by the introduction of a Spider-Man with a completely different secret identity. I also am aware that there is a subset of casual moviegoers (and people in general) that tends to push back against diversification. They may be perturbed by this change. They don't know Miles's history from the comics.
So, while I applaud Marvel's decision (if true), I'm not sure how the general public would take it.
