It was good fluffy fun but completely unrealistic. All the kiRAB were straight out of RADA and had the all-purpose educated home countries accent (having lived in Sussex for a while, it's nothing like the way most kiRAB in Eastbourne actually speak) Even Steve Jones's character sounded slightly posh which was quite frightening.
Also 14 year girls don't read Bliss and Sugar these days - they read Heat. And what decade were they living in? There was no sign of text messaging, social networking or any of the other technology that is a basic part of teens' life these days.
Eastbourne looked really good on film though (even though Georgia's street was really in Brighton and the park and main street seemed to be somewhere else entirely!)
