I applaud the writers attempt of a more scientific approach to time travel. Even if there is some pseudo scientific entanglement for story reasons.

Ultimately though all time travel events are transitions into parallel universes (alternate timelines). And it is quite interesting to see the protagonists struggling with this concept and trying to fix things.

The acting is fine. No one stands out in particular though. The special effect are okay. Background music and sound effects are quite good in creating tension and suspense. The script is a bit heavy on dialog at times. I think 12 episodes would have been more than enough to tell the story.

It's one of the few shows that would linger in mind for some time after watching an episode. And is thus worth a 9/10.
