This is the kind of show Fringe needs to put on to keep those American Idol viewers sticking around. Have a psycho killer on the loose that it is not just a simple murderer, but also not too unbelievable that even the biggest sci-fi geek would disapprove of.
My only real complaint here was that the comedy element of this show seems to disappearing. There was very minimal dialogue between Walter and Peter, and outside of a few sarcastic Peter Bishop lines, not a lot of laughs tonight. I understand there needs to be a serious tone, but every once and awhile JJ Abrams could throw us a joke.
