Spider-Man: Into the Spider-Verse is the best Spider-Man movie in a really, really long time. Yes, Tom Holland's introduction of Peter Parker into the Marvel Cinematic Universe via Spider-Man: Homecoming was a much-needed jolt of sprightly energy, but was nonetheless a little hamstrung by its very inclusion in the MCU. Spider-Man: Into the Spider-Verse, however, exists in a universe all its own. Well -- universes.
"The question we all had was, why another Spider-Man movie?" one of the three co-directors, Peter Ramsey, told Thrillist. "There have been so many, and so many good ones, that the only real reason to do it was to do something which would be a real break with those and allow you to tell the story in a completely new way."
Believe it or not, it's easier to just watch the movie than to try to explain the mechanics of it in words. An attempt: In a universe not too far off from our own, an aged Peter Parker dies attempting to stop the Kingpin from opening a tear in space-time, allowing individuals from other dimensions to fall into his own. Miles Morales, Marvel Comics' newest version of Spider-Man introduced in 2011, witnesses Parker's death and takes up the Spider-mantle, working alongside a number of other displaced Spider-characters stuck in his world -- including Spider-Man Noir, Spider-Pig, the robotic SP//DR and her human companion Peni Parker, and Gwen Stacy a.k.a. Spider-Gwen -- to put all of their universes back together again.
