I'll be interested to see how Man Of Steel
does. I do think that the current "dark" treatment of much skiffy material which has it's basis in less jaded times has become tedious, but it's also true that wandering very far afield from that stance these days is often the kiss of death for any production that requires a huge audience in order to generate a profit.
I like a lot of that so-called "realism" (which is actually just as escapist as the old stuff, rendered in a different palette) but it has, for the moment, crowded every alternative out of popular movie fantasy as effectively as McDonalds and other fast food have come to dominate the big food service industry. The exception? Animated movies putatively targeted at children.
Myself, I'm looking forward to the upcoming Oz
movie but I fully expect it to be a box office bomb. It's visually bright, colorful and clearly a whimsical take on the material - too pretty and too happy by half to amuse the young adults who must be persuaded to consume it en masse
. Burton would have found his way to whatever sickliness could be found in the story and visual design and the thing might have had a shot. Raimi, peculiarly enough, is too much in love with the native tone of his source material for this to succeed.
