Superman doesn't need a "visionary" director to put a new
twist on the character and make him
relevant (as if an illegal, adopted alien whose main villain is a disreputable, xenophobic billionaire who was once the president of the united states isn't relevant
).
Singer and Snyder both tried to make superman
relatable by turning him into a moody mope, heck good ol' Zack went a step further by adding his own unique touch of nihilism onto the character even though he hit the audience on the head with club in MOS on how Superman is the literal/figurative symbol of hope. Ironically they both ended up over using the
"I. AM. JESUS!" shtick that Donner used 40 years prior. Yeah I think I'll pass.
It seems to me that WB have tried everything but sticking to the basics, everything but giving us an honest to god fun movie about a
likeable and not necessarily relatable character that happens to be the dream and the dreamer
JJ has kick started 3 major franchises successfully but seems to drop the ball on the follow ups so if he is a smart man (I think he is) then he has learned from his mistakes and would shepherd the project into realization then take a step back and let another talented director carry the baton. All I know that from the scripts he wrote - hokey as they may have been - got the character of CK/Superman right and featured plenty of fun and levity and honestly that's what I and most of the fans need right now, get the character back on it's feet first then try to make it soar into the sky with some "visionary revisions".
