Galley Friend P.G. suggested to me last season that Fringe could be evolving from a mildly-interesting-X-Files-spawn to a seriously interesting and original sci-fi story. The inflection point P.G. was intrigued by was the moment when Fringe opened up the the multiverse and introduced the idea of a war brewing between the (so far) two universes. Since then, the series has only gotten more engaging.
Two minor questions:
(1) Leonard Nimoy plays William Bell in the show. But in the Fringe world, we've seen that Star Trek exists. Spock-Nimoy-Bell . . . who is real? Who is pretend? Head hurts now.
(2) What do we call the other earth? Hercules refers to it as Earth 2. I've been calling it Earth Prime. Maybe we need to consult Marv Wolfman.
Bonus nerd question: Is the Observer something like the Monitor? Only time will tell!
