About

"A shaky start that earns real heartbreak"

A time traveler is sent back from a ravaged future to stop the release of a virus that will kill most of humanity, but altering the past proves far messier than expected. It starts as a moody, twisty chase thriller and gradually deepens into something stranger and more emotional, layering paradoxes, doomed relationships, and philosophical questions about fate. The pacing tightens season by season, trading procedural time-loop mechanics for genuine heartbreak. It rewards patience: early episodes are serviceable, but the show becomes something far more ambitious and affecting as its mythology locks into place.

Watch it for

the way its time-travel puzzle box pays off with genuine emotional stakes by the end.

Maybe skip if

you need a strong first season, since this one takes time to find its voice.
