What they’re saying

“I'm 100% certain that the Sinister Six will be the villains of Spider-Man 6 which will probably be Holland's final movie. The MCU kills most of its villains and surprisingly none of the MCU Spider-Man villains have died so far (yes, Mysterio too). It can't be a coincidence. I'm betting on the team being Vulture, Mysterio, Scorpion, Shocker, Rhino and Kraven or Mister Negative (whoever ends up being the secondary villain of SM5).”

“Spidey vs Sinister Six is something I can see being the finale for the franchise. It would be perfect.”

“The Sinister Six for Spidey 6 would be perfect. And by then he'll have a pretty solid lineup of returning villains to form the group. Vulture, Shocker, Mysterio, Scorpion, maybe Kraven for Spidey 5? Then in Spidey 6 someone like Mr Negative or Kingpin assembles them.”

“Thing is the Spidey vs Sinister Six story has become pretty overused and saturated by now. We already kinda had that in NWH + Insomniac's Spider-Man + Into the Spider-Verse and now it looks like we'll get something similar here too.”
