I understand why they're rebooting the Spider-Man franchise; the old star and director weren't available, at least not for whatever price the studio was offering, and Spider-Man is too valuable a property to be left on the shelf for long. So a new director and star are taking a new approach (for example, emphasizing Gwen Stacy rather than Mary Jane Watson as Peter Parker's love interest). I'm more than willing to give Andrew Garfield a chance as the angst-filled web-slinger.
But what I don't understand is this: why do they always, in a case like this, feel they have to go back and do the origin story all over again? It's only been 10 years since Tobey Maguire's Peter Parker was bitten by a radioactive spider. Look, we know how Peter Parker became Spider-Man, just as we know about Bruce Wayne's parents being shot and little Kal-El being rocketed away from the planet Krypton just before its destruction. Spider-Man is probably the third best-known comic book superhero behind Superman and Batman. You don't have to be a comic book fanatic to know the story. Why not just start in medias res, to use an academic term, and tell a new Spider-Man story, and give the audience a little credit?
