How can Walter and Michael alter history by going to the future of an already altered timeline?
I have to admit that this one point has been bugging me since reading it earlier this morning. As many others have pointed out, one of Fringe's major flaws was the lack of logic concerning time-travel. I keep trying to wrap my mind around it, to find some manner that it makes sense, and it doesn't.
It is, as I said, the show's major flaw. That still doesn't change the fact that it was still a better series finale than many others I've seen over the past twenty years.
