At times the story is weak and slow and more of a de ja vu for the teen sci-fi genre. But then BANG! there's a witty joke or if you're lucky there will be an unexpected twist or heartfelt confession from one of the most lovable characters.
Disc one of part one and disc two of part two, in my opinion, have the best episodes with the better half of the story (for some reason it felt like two seperate stories that had been slapped together to make this series longer and more complicated than it had to be) I loved the show, even with its flaws. It's superb and an absolute guilty pleasure.
