Successfully rebooting a franchise is one of the trickiest tasks in Hollywood, which explains why studio executives only tend to attempt this when they’ve exhausted every other option in their arsenal.For example, before consigning themselves to recasting Peter Parker and rebooting the Spider-Man franchise in 2011, Sony gave Sam Raimi and his cohorts several years to try and correct the course of the Tobey Maguire-starring franchise after the lukewarm response to Spider-Man 3.
