What was great about Seven of Nine?

What was great about Seven of Nine was that she was both innocent and corrupt.

She was a Data or Spock-like character, in that she had the innocence, but she was also deeply corrupt, she was a mass murderer as well.

She was a character who was deeply human but had no moral compass, 'cos she was raised by wolves. So, I think that made her extra interesting.

It was an instant success. We had a backlash initially, when the photographs came out of Jeri Ryan, a lot of people accused [us] of turning Star Trek into Baywatch. But then, I think, once they saw the character developed, and they saw that Jeri Ryan was a terrific actress, they started to look past the Las Vegas-like costume, they saw there was a real character there, and that all went away and she was very successful.
