In the meantime, word has slipped out to the Web today via Empire Online that plans for a remake/reboot have been shelved. Writer/Producer Dean Devlin sounds off a bit in the article (you can follow the link for the details if you're interested), and he may know more than he's willing to divulge. For my two cents, Stargate was always a kinda/sorta borderline success as a feature film: I think it did much better on home video and (obviously) once it was launched as a television property ... but a remake? A reboot?
I won't belabor the point here (I'm frequently tinkering with a deeper piece regarding my disfavor of reboots) but I will say I just don't see the potential audience for a full relaunch. This isn't to say that I wouldn't like to see the franchise revisited in some way; I just have to question the viability (as a realist, not a SciFi fan) of unearthing something old with little more than what tends to amount to a few fresh faces.
Feel free to sound off should you feel compelled.
As always, thanks for reading ... and live long and prosper!
