It's not remotely plausible, but with Willis' McClane leaping onto the tailfins of passing jet fighters and bringing down helicopters by launching police cars at them, there's enough stuff blowing up that action fans won't mind much.
There is nothing like a strong female lead and in Nikita they give us two beautiful, intelligent and compassionate women who are strong enough to stand up for their selves and for each other against a secret government agency.
This is the best show on TV. If you are not watching, you should rent/buy season 1 and then the same with 2. It does start off a bit slow but by episode 5, it is amazing. I recommend this to anyone who likes a show with action, drama, suspense, and humor. A combination of Alias and '24' but even better.
