I have often felt like the show hasn't done the best job of diversifying the cast in terms of personalities when most of the main cast can be summed up as "teen super-scientist" type. Especially when said super-scientist types all inevitably also end up in costume and in action with Peter. I mean, Miles, Gwen, and Anya all have personalities but I'm not sure if they're distinct enough to really standout from each other most of the time.
It's why I was disappointed that Peter went back to Horizon at the end of season 2. I was honestly looking forward to seeing him back at Midtown and interacting with kids that have different interests or experiences then the kids in Horizon who, really, aren't all that different from Peter. But other then Flash the show never did anything else with Liz and Randy. What was even the point of that Screwball episode? Randy got Peter his job with the Bugle but that was short lived too.
That's not even getting into how Peter, the main character, more often then not needs to juggle screen time or get saved on his own show by other super-scientist Spider-Heroes. Like, what is even the point of Spider-Man then and what does he bring to the table? And then when you inevitably re-focus on Peter, because it's his show, the other Spider-Heroes just end up being wallpaper.
