I voted "Meh. Useless." But then, I'm not much of a fan of kids on scifi shows in general. Didn't like Wesley Crusher or Naomi Wildman either.
Jake Sisko was a bit better...but I think that was because he 'grew up' on the show and had more adult-themed interactions later on.
But generally speaking, I'm bored by the kids storylines on scifi shows.
Thank God nuBSG didn't stick in that annoying kid that was in the original BSG series. Dodged a bullet there, I think.
