Did Smallville ripoff Roswell? I don't mean the concept, but rather it's execution. I remember back in 2001 when Roswell moved to UPN and Smallville premiered on the WB. The similarities to Smallville and Roswell was downright spooky. Over time, Smallville grew into it's own show. That said, what do you think? I'm guessing Smallville was a second attempt at a Roswell kind of show. Instead of the Roswell aliens, Superman! Obviously, a larger audience by default.
