2) Spider-Man
The big reason 2012’s The Amazing Spider-Man was such a pointless endeavour was that the webslinger’s origin story had already been brought perfectly well to the screen just 10 years earlier.
Sam Raimi’s 2002 movie might have taken some liberties with the character (organic webbing) but it did offer up what is now the definitive version of his beginnings for most fans. Peter’s initial arrogance and misuse of his powers directly leading to Uncle Ben’s death is such a tragic scenario that it brings a lot of weight to his mantra of ‘with great power, comes great responsibility.’ This element was of course something that was sorely lacking from Amazing’s version of the events. As is evident here, Spidey’s guilt, rather than his quest for vengeance, is at the core of his journey to heroism.
Thankfully, next year’s Spider-Man: Homecoming will forego serving up yet another version of this story.
