There have been many other shows like that for years, none last too long. They just don't advertize themselves that way too often.
Smallville did and lasted 10 years, a record.
Let's face it, Buffy sort of was like that too.
The 4400 was pretty much "X-Men created by mysterious abductions".
Alphas, still airing, is pretty much "X-Men called something else".
No Ordinary Family only lasted one year.
The Tick? The Cape? That Wonder Woman pilot that went nowhere?
Since it's Marvel, though, I'm thinking...Return of the Hulk to TV?
I wonder, are the guys at DC kicking themselves over losing Joss' attempt to do Wonder Woman for the big screen? Sure, it still could've flopped, but it might not have.
