Anything could be escapist fun; you don't need an existing franchise for that, for anything but bare name recognition. Everything else could be changed.SG at its best, particularly SG1, was good escapism fun.
What happened to that actor who played the Teen-aged Jack-Clone? Has he done anything outside of that one episode?
He's in the Twilight movies! (So much for his street cred around here.)
In other words, he's in something more profitable and popular than Stargate has ever been, so there's no reason he'd come back to this dead franchise.
