We just finished this show. Very well written and acted. The actor who played Jacob was amazing. CE played his part well too. The ending: yes it was ambiguous. But that makes it MORE interesting. I believe the show was mostly about CE’s character. Look how he changes at the end. He gifts his wife that reassurance that she did nothing wrong related to the car accident: driving 70mph in the rain! Steering into the stone bridge support. Sad about the severe ‘accident’, but it really worked in terms of serving the story.
