Enjoyed the pilot well enough.
But I think the show is going to have a real problem sustaining a credible threat from the Division. Nikita knows too much about them, including seemingly all the bigwigs and their operational doctrines for it to take longer than one season for her to bring the Division down. Especially considering she has perhaps two moles inside it.
If Nikita knows who the leader of the Division is why doesn't she kill him? It is the same problem that Sidney faced in Alias, and which that show wisely ended early by bringing SD-6 down midway through season 2.
