In addition to the issues of morality and identity, three "isms" are covered in the two series, these being Utopianism, Dystopianism and Environmentalism. The first series focussing more on the identity and morality of the characters, and the second dealing with the battle between good and bad and also the ambiguity that sometimes exists between the two.
In the first series, while trapped in the past, Alana struggles to fit in in the new time, a feeling many teenagers struggle with when trying to be understood and establish an identity. From the outset there is always a clear distinction between right and wrong. Silverthorn is shown to be the antithesis of Alana's moral character. He is the opposite of everything she is, only out for himself and will manipulate others to get what he wants. The character of Eddie brings a different element to the story. Although he begins working for Silverthorn, it comes to our attention that he is only with Silverthorn because he fears him, thus Eddie at times is shown to be an ambiguous character, swapping sides when it will benefit him. Petey is an impetuous 10 year old and is being bullied at school, at one point the steals Alana's transducer so he can teach his bullies a lesson. When he causes a fire, Alana and Jenny tell Petey that what he did was wrong, he shouldn't have stolen Alana's transducer and that using violence is not the way to sort out ones problems.
In the second series three time periods are shown, our own present time, the year 2500, and the year 3000. The year 3000 is shown to be an idyllic pleasant place to live. Although it is a beautiful time the people of that time are repairing the damage caused by the Great Disaster, which occurred in the year 2500. In the year 2500 the majority of the world has become a polluted wasteland and the wealthy live on moon bases, while the rest of the people struggle to live on the polluted Earth. The year 2500 shows a possible future for the world if the environment is neglected. Although the second series shows two extremes, a Utopian society in the year 3000 and the Dystopian society of the year 2500, it also shows that the Utopia was born out of the ruins of the dystopian society, showing there is always hope for the future.
This comparison between the two society serves to teach the viewer that the effects of the past and the present will determine the future of the planet. This point is pushed once more at the end of the second series, when Jenny and Petey begin clearing out all the poisonous cleaning materials from their mother's shop. When asked why they explain how bad things were in the future and that is was people in the past which caused it by never stopping to think about their affect on the environment.
In conclusion the main topics covered in the series are the issues around finding ones identity, understanding how to behave in a moral way and also to instil a code of ethics in the viewer. The second series serves to show how the world will be it we keep abusing the environment and polluting it without a second thought.moreless
