Following Olivia's near escape last episode and Peter's discovery that the Olivia he's with is an impostor, there were many directions the show could have gone. The two Olivia's could remain trapped in opposite worlds, with Olivia still trapped in the other world and Peter trying to find an angle on the other Olivia. All sorts of good stuff could have gone on. Instead, one episode before the midseason finale, the writers decided to let things go, putting both Olivias on the run.
"Entrada" is probably the most exciting, fast-paced episode of the season as we see Olivia escaping with Broyles and the other Olivia tying up loose ends before her getaway. At the same time, there's lots of great acting and emotion during the slower scenes. By the end of the episode, the Olivias are back in their proper places.
The aftermath, however, leaves a mess which has to be cleaned up. In the first universe: Olivia is back and says that Peter is the reason why she stayed alive. How will she feel when she learns of Peter's relationship with the other Olivia. In the second universe: Broyles is dead. The other Olivia, before leaving the universe, expresses to Peter that what started as a job progressed to something more. Is she really harboring feelings? And after seeing the other universe and seeing them in a closer, personal way, how will she feel about trying to kill them?
After next week's midseason finale, Fringe will be moving to Fridays on January 28, and possibly going into the homestretch of the series, seeing as the ratings have been incredibly low. How will the show proceed? The doomsday device has one more piece, and everything is in place for the war to proceed to the next level. Will the world-switching format of the show change? "Entrada" featured alternating blue-red credits, but the format wouldn't really work if it's a monster episode, unless, of course, the writers put the foot to the ground and go all-out with the war.
Score: 9.5/10
