Manifest's "Vanishing Point" is excellent - the best episode since the Pilot. I can honestly say that I wasn't bored during a single moment of this episode, and I found it to be quite compelling and well-written.
A couple episodes ago, we were introduced to a few new storylines: Michaela's visions and the all-knowing "Major" giving orders and manipulating Autumn into spying on the Stones in order to get to Cal (the "Holy Grail"). I was positive that this storyline would be as dragged out as the missing passengers, but to my immense surprise and delight, they started to wrap it up almost immediately and deliver some much-needed answers!
So far, the second half of the season has been loads better than the first, and it's showing a chance for redemption for "Manifest" - as long as the storylines continue to be full-speed ahead without the family drama and sappiness.
