Damn..peeps in this thread are PIIIICCKKKY.
Why is it such a crime for someone's favorite movie of all time to be Donner's Superman? Seriously, it had flaws, but it was a good movie. Some people like Scarface, which I thought was crap (and I love Pacino). It's a preference, get over it.
As far as Geoff Johns...he's incredible. I do not like the direction Dan Diddo is taking DC comics with his damn multiverse destruction, but not really a destruction...but Johns is gold.
Having said that, I completely agree that Donner's version needs to be just that, his version and they need something new. BUT that doesn't mean you rewrite cannon to separate it from Donner's version. Keeping Jonathan Kent alive, changing the fortress and all the crystal stuff, you can do all that. But other things must be left alone. I personally don't have a problem with Superman having crystal structures as buildings, but I do have a problem with the whole planet being Antarctica.
I think that doing a Superboy movie is implausible and not viable. If you do that, you ruin any chances of a Superman movie, because you've seen everything. I am okay with Superboy in the comics or a cartoon, but the big screen is reserved for the big dogs, and Superboy is not a big dog like SuperMAN.
