I would have to say this is an average TV series. Not much gets explained, apart from all the adults disappearing, not much happens.
I feel the writers tried to get in a lot of social issues
Gun amnesty and the pros and cons of both
Teenage sex, and the problems associated
Gays, race, religion, money, poverty, drugs
But in saying this it is slow paced and boring.
If I wasn't stuck to the lounge with the flu, I would NOT watch it and I certainly can't recommend it.
