Thanks for the correction, Paul. Think I'd misread Wiki on the subject. Frankly, new characters makes much more sense. I didn't quite understand the premise of choosing the existing ones in the first place!
Personally I adore Parkman,
I think what set me against Parkman was the episode in the future when he was one of the bad guys. Which is grossly unfair of me, I know.

But up till that point I'd found him fairly inoffensive.
