Well, this was fun! I thoroughly enjoyed this and will be tuning in for more. I do wish the dialogue was snappier and the show had a bit of a sense of humor about itself, but Nikita is awesome (I've had a long-term girlcrush on Maggie Q, so that undoubtedly helps), there are things blowing up, and Shane West is pretty (I can see myself shipping his character with Maggie's in the future, if the show chooses to go that way. Especially after she shot him :P). I really liked the Ukrainian convict girl as well (I take it she is the other major female character?).
Wiki article says that some critics compared this to the Dollhouse which leaves me scratching my head madly. I mean, if Nikita was a brainwashed sexual slave obedient to her evil masters (who were all woobies, honest!), maybe, but as it is, it's a kickass show about a kickass woman. A show that does not make me cringe.
I am kinda imagining an IRIS cross-over in my head now. :)
ETA: You guys win. I am going to give Vampire Diaries another chance. I am going to watch s2 opener.
