As the resident Hitman fan (okay, there may be others but dammit I'm posting here first), I'm gonna say the Hitman movies. Haven't seen Agent 47 yet, but I'm pretty sure I can figure out it is a movie set up on spectacle and explosions.
Anyone who is an actual fan of the Hitman franchise knows damn well Agent 47 actively tries to avoid spectacle and explosions. He is supposed to be a phantom, an urban legend. He doesn't get the girl, and he doesn't go around with companions. He is a stone-cold professional. They should play like a crime drama, not a Die Hard movie. And for fuck sake Hollywood. I like Timothy Olyphant just fine, but why not get David Bateson, the voice of Agent 47 to play the role since he looks almost exactly like Agent 47 anyway?
Also? League of Extraordinary Gentlemen. It takes talent to fuck up things on that great of a scale.
