Olivia Dunham in the pilot was a different one then the one from episode 2 season 1. Anna Torv was hailed the new Cate Blanchett by the critics and she made the pilot.

In comes Jeff Pinkner, showrunner from episode 2 season 1, and he decided that Fringe had to be about the Bishops, nothing done with Olivia’s Backstory or link with the big Arc, Anna found it hard to play the closed off Olivia Dunham, but was forced to, with Pinkner only last year saying somewhere obscure that he found it hard to watch the way Anna was treated. But he did nothing , not defended her, not wrote a decent storyline so that the viewer could understand where she came from.

So thanks to Pinkner, it comes up very time, when they say something positive about Anna or now with the Alcatraz lead.

Olivia Dunham is/ was a closed off, introverted character, what she did an does with Olivia is awesome, the depth Olivia had, comes from Anna’s acting not the writing, like for Noble etc.

So we have Alcatraz, and so far Rebecca has more backstory and connection with the big Arc in 4 episodes then Olivia has in 80 plus episodes.

Difference: Alcatraz has a Female showrunner, and I bet if Fringe would have had one , we would have known far more about Olivia from the start, wich would have made Anna’s life a lot more pleasant, and probably would have kept Fringe on a Monday or Tuesday.
