TV - my head hurts!

Am I alone in thinking that "Fringe" has taken a step too far?  The idea of a parallel universe full of doppelgänger was OK provided the two were kept apart but now we have "our" Olivia Dunham over there and "their" Olivia Dunham over here it has, at least for this viewer just become too much to handle.  It may be that Americans can pick up on the nuances to be able to tell whether we are dealing with "here" or "there" but (unless they show that shot of the zeppelin) I can't and what used to be a good sort of new-style X-files has just become too complex.  And as for "The Event".....!!
