This is another super expensive and excellently executed production of a time travel drama that fails due to its plot inconsistency. It suffers from unnumbered time paradoxes that end up to look like continuity errors.
There is not a single episode that doesn't cancel what you've watched on the previous ones and doesn't raise more questions than those that is supposed to answer.

The characters cancel continuously their own actions and on top of that they look like they are amnesiacs, unable to remember what they did themselves not even in the same time line.

The production, the music the special effects etc will blow out your mind, but that's just all there is. Don't expect to understand anything and don't bother to explain the end because there is no point on doing so. It is another time travel drama ( along with Signal and Kairos ) that its plot doesn't make sense.

3/10 from me just for the sake of the expensive production.
