It's not a good TV series if you have to read sub-notes/wiki fan page

I rewatched season 1 & 2 to try to get a grasp on the various plot lines involving all of the characters without looking up online resources such as wiki or fanpages. It still lacks a coherent narrative string that keeps you keyed into what each character's purpose is and how they're all interrelated.

The series would be better served using a narrative device involving One central character who ties the series or at least the major plot line along. Something like in Star Trek where Captain Kirk or Captain Picard would open up an episode with a Captain's Log summation of what was going on.
