I think, if you’re going to get a director to concentrate and adapt something like this into a big budget Hollywood film, Justin Lin is a pretty good choice.
Honestly, the concept of the original source material is pretty straightforward enough. What matters, I think, is getting the tone right, and balancing the insanity of all of the crazy superhero type stuff with the casual, everyday, civilian, conversational and philosophical stuff.
With the Fast 5, we know he can definitely pull off the crazy action. But, as shown with Star Trek Beyond, particularly with that opening scene of him narrating a short montage of the growing monotony of daily life on the Enterprise, and him contemplating mortality with Bones, he can definitely do the heartfelt and down-to-earth stuff. I mean, that monologue almost feels like something Saitama would narrate to the audience, only with some different words and in space on a starship.
I feel slightly OK about this. We’ll see how it goes.
