Give me a break, guys.
If there is ever a category for lamest retcon in the history of sci-fi/fantasy television shows, it should go to FRINGE.
"The boy must live" suddenly means baldboy Michael? Because he must return to the source like Neo and then everyone will see the error of their ways and then the Observers will never exist?
Of course if the Observers never exist, then the series of events caused by them will never exist, which means when Walter takes Peter back through the portal there will be no September there to save them and so NONE OF THIS WILL HAVE HAPPENED!!!!!
But of course that's not how it will go down because they will just make it fit even if it doesn't.
The writers think you are all stupid.
And perhaps a lot of you are. Or you will just eat up anything because it is the show you love.
For you guys, why do you read reviews? Why do you read comments about the show you love? Just to read someone agreeing with you?
Anyway, what a mess. What a joke of a final season. The writers, and any critic who praises them, should be embarrassed.
If I had to rate this episode, and I don't, I'd give it:
0 out of 100
A massive turd was just deposited into the mouth of a show I once loved. Thank the gods it is over next week.
