Part of me is starting to wish that the last 10 years of Smallville have all just been one big setup. They spend 10 years giving us a generally mediocre show, that has flashes of brilliance every now and again, and constantly teases us with Supes mythology, and by the time that show ends, the fans are literally dying for a legitimate weekly Superman show - Red and Blues, secret identity, Lex Luthor, the whole nine yards.
What better time to release one?
It's been joked often on the internet that Smallville should have been re-named "Metropolis" by now, seeing as the town of Smallville barely features in it anymore. Maybe that's not such a bad idea. For all people on the internet can moan about Welling's acting, or the writing, I think if they ditched the whole "No Flights, No Tights" mantra that seems to have plagued Smallville for the last 10 years, and they were allowed to cut loose and make a full on Superman show without tip-toeing around the mythology, I think they'd be capable of making a damn good show. It probably wouldn't hurt for a show like that to have access to a larger budget, but I think they could pull it off.
It would be a bold move to "evolve" the show, and re-brand it from "Superman - The Early Years" into "Superman", but one that I think would really pay off.
Basically, if the rumours of next season featuring Darkseid/Apokolips are true, then it would be an ideal opportunity to turn Clark into Superman. I mean, Apokolips would be such a massive threat to Earth - much more so than Zod's army ever were - that Clark has to fully embrace his destiny in order to defeat Darkseid. I'd love to see Clark, in the season 10 finale, pull on the Superman outfit, and give a Doctor Who-esque "This planet is protected" speech, before leading the JSA/JLA heroes against Darkseid.
After that, use whatever maguffin to create Clark's dual identity (hell, they've been using them for 10 years, why stop now?), and re-brand the show as Metropolis season 1, with the same actors, bringing us a proper Superman show.
I'm well aware that it would never happen in a million years. There'd be far too many things getting in the way of making it happen - budget constraints, the alleged fact that Welling won't wear the suit, the difficulty of getting the actors to commit to maybe another 5-10 years of the show if it's successful, the rumours of a Nolan-produced Superman reboot on the big screen... etc
Hell, I can dream, can't I?
