Nikita is good right now, but it is always a much stronger show during the last four or five episodes of each season. And it looks like season three will be the same way.
Overall(so far) I think season three has definitely been the weakest season of the show, with a first half that was a snooze fest. I almost stopped watching. But the last few episodes have been quite good. Despite the ongoing structural weakness of Amanda being a weak villain with weak motivations.
