You might wonder why so many films now are remakes or reboots of old franchises. Usually; it's because the original films are old and with modern technologies and hindsight, their stories can be expanded and made into something better.
Remakes can work. Invasion of the Body Snatchers, John Carpenters' The Thing, Scarface, True Grit, The Fly and many, many others have proven that remakes can work, given the right circumstances, attention and love.
But a question that lingers is; if a film has a legitimate problem, in that, even with all new technologies and hindsight, if it has no chance of surpassing the original, is it worth remaking?
