I don't really know what I think of this season's Fringe. The last few eps, as you said, are pretty good; but, I just can't get a handle on where the heck they are going with things. Everything seems so random and unconnected.
We did get the info, at the very end of Friday's ep, that Robert Jones is probably behind what went on in that town; but, Why? I feel like I'm still waiting for them to start the season.
But the multiple timelines between the universes make this a completely screwy "multiverse." I wonder if we're not going to see something out of other sci-fi series or books... sort like Heinlein's "Number of the Beast."
