Hear of Superman the Movie much? I say give him a shot.
Hey, don't get me wrong, the guy's got the touch alright. LETHAL WEAPON may be the greatest action movie ever made.
However, directing and writing are two different skills, and the fact that he can do one does not necessarily mean he can do the other.
At least he isn't likely to have Superman decapitating someone in a shockvalue splatterfest. Unless Johns coaches him to do so.
Again with the Johns diss. You know, people that slam Johns for having no respect for comics history need to have a nice, hearty bowl of shut-the-hell-up.
Geoff Johns was the guy that killed off that leather jacket and tattoo wearing wank we've had since ZERO HOUR, and gave us a REAL Doctor Fate, and did so in a manner consistent with what we know of the Hall family, namely, their tendency for reincarnation. He was the one that did the impossible and restored to the DC universe the muddled to hell Hawkman; not as a different character with the same name the way Morrison had to, but as the original character that simultaneously drew on Golden Age and Silver Age Hawkmen, keeping both in play. He was the one that restored the original Doom Patrol to DC after Byrne's reboot, saying that the appearance of the Byrne Patrol was a "flux" caused by Alex Luthor (and the existence of the original patrol is still in canon). Best of all, Geoff Johns was the one that restored Hal Jordan to his proper place as Green Lantern, one of the greatest characters in comics history, after decades of absence.
It was Geoff Johns that used such great classic foes as Sinestro, Kobra, Abracadabra, Hector Hammond, Per Degaton, and others, keeping them in their original costumes and with their original motivations. His SUPERMAN/BATMAN story made Kamandi a possible future again and did not involve Kamandi becoming Tommy Tomorrow or some other such nonsense. He brought back, too, the original Legion of Super-Villains. It was his idea to give Power Girl back her Earth-2 origin. It was he that in INFINITE CRISIS, gave us back Earth-2, and yes, Earth-2 is here to stay.
The list just goes on and on.
Granted the guy has never written comics before and the industry does seem to have this thing where anybody who's been in Hollywood is somehow automatically good for comics regardless of how well they actually fit the material they are given. But in Donners case the guy has a love and familiarity with Superman that puts him head and shoulders above guys like Wedon and Strazynski.
Well, above Straczynski, anyway.
