This has a great storyline and I imagine that the inspiration was taken from the book A Time Traveler's Wife.
Episodes 1-10 are GOLD, however episodes 11-12 crashes the entire storyline into a wall and just gives us a bad ending with a "love will concur all" sticker. So yeah... be prepared to be disappointed.
This story gave a lot, everyone on set was great actors and directors included, but the writers...not so much, or they were hella rushed.
The whole thing lands on a meh for me...
