Without a doubt, the trippiest show on TV right now is "Fringe," (Fox, 9 p.m.) which takes place in this dimension and a different one every other week.
Tonight, the opposing storylines come to a head as Faux-livia, aka the Olivia from the other universe, has been exposed while our Olivia is about to get executed on the other side.
For fans who have stuck with the show, it's a great payoff for a few seasons worth of patience.
When "Fringe" first debuted, the pacing was too slow and it seemed to be little more than a bad "X-Files" clone. But instead of dropping little breadcrumbs of clues, the producers decided to dive into the mythology of the series, and that's when it really started to pay off. There are still mysteries every week, to be sure, but at least the viewer can now see the bigger picture.
Perhaps the best aspect is that the alternate universe isn't evil -- this isn't a "Star Trek," "Mirror, Mirror" type deal -- but rather it's populated by our doubles who are merely trying to survive. Our universe is not any more good or evil than the other one -- just a little more structurally stable.
"Fringe" has also benefitted from great performances from stars Anna Torv and John Noble, who give us very different takes as Olivia and Walter as well as Faux-livia and Walternate.
I can't wait to see how they end this wild ride.
