One of the really important aspects of the story of this show, is the characters' new abilities and the effect they have on their surroundings. Some could say this sounds a lot like the show, Heroes, and they would be correct (however, I would like to point out that this show came out two years prior). In the beginning it seems very random, as not all characters seem to be showing signs of developing an ability, also the type of abilities they develop doesn't always come across as beneficial, more like the opposite. Some abilities come off as just plain destructive.
However, as the show progresses, it becomes clear that there is most likely some kind of master plan behind it all, it just takes time to see the cause and effect of each individual event and link them together to see the big picture.
3. Ripple Effect
Touching a bit on what I said above about the characters' supernatural abilities and how it all seem to be linked to one great master plan, the way the story is mostly told is through the ripple effect. Small, seemingly unrelated and insignificant moments eventually causing a greater impact. This is one of my favourite plot devices, because I like seeing how change comes about, and how so much of it can be traced back to these little moments.
To start with, the show mostly focuses on the 'returnee of the week'. We are given a backstory, the reveal of a new ability and see that character's choices regarding their ability. We see the initial outcome of the situation, good or bad, and it seems pretty final. But then the ripples start, the individual stories start to connect and form a larger pattern. What I love especially about this is the unpredictability of it all. Because sometimes good acts will have terrible consequences, other times terrible acts will have good consequences. You just never know where it'll lead.
4. Friend or Foe
Again, touching upon what I wrote above. But like there's a sense of unpredictability on whether an event ultimately will had a poistive or negative effect on society, there's a similar uncertainty in terms of some of the characters.
Tracking down a decent enough trailer for this show was pretty time consuming, and I apologize for the low video and audio quality, but at least it's a good promo, and hopefully it will be that final push to get you to give this show a chance...
