Naomi was fine I thought.
The Borg Kids were the worst thing Trek has ever produced, Westley Crusher was annoying but Wil Wheaton a G so i can give him a pass.
I'll agree on the point of the Borg kids. That was just redundant to no end. There was nothing they contributed that Seven or Naomi hadn't already done.
Heck, Icheb was pretty much the Borg Wesley Crusher, except was even more dull somehow.
