Firstly, need to say that i haven't see La Femme Nikita original tv series, so i don't know if it's copy, better or whatever. I will review it as a new series, never seen before.
All episodes are basically, missions of Nikita destroying opetations of Division with little clues of the main story now and then. Sometimes it's just has to do something with hers or Alex's past and are not really necessary for the story. Nikita, is a kick ass woman who beats big numbers of guys at each episode with sometimes not even a weapon her just because she is too awesome. And while this is something that can't happen it was really cool to see such a strong heroine around.
Unfortunately , big part of the series is Alex. A character which personally i didn't like. She was Nikita's secret apprentice trying to destroy division from inside. The thing is, that around Christmas the show should had changed name from "Nikita" to "Alex". Everything was around Alex almost until the season finale. And when i thought that finally we will get rid of her, they give her a new important role for next season.
Apart of that, i can say i enjoyed the show. It was full of action and an really interesting story at the same time. All the actors have done good job with their roles, especially the main ones (except Alex.she could do better). There was a period were CW lost some viewers because the show didn't have enough romance to keep the female viewers interested, so they had to increase its level a little after Christmas. They messed it up a little, when Nikita hooked up with one of the FBI guys, when was obvious she would be with Michael at the end. This certain move didn't make sense, but i guess they had to do something til Michael turn to the good side.
The show has currently signed for a 2nd season and there were times that its view ratings were bigger than Vampire Diaries as well.
