I enjoy science fiction and time traveling stories, but this series was so disconnected and was incredulous. It was like after season 3, the writers were just winging it.
Acting was terrible! Cal’s smiling in every scene, even when things were bleak , was beyond the pale !
I finished season 4 , just to follow the series to the finale, but the finale became predictable.
Also, plane rising up from the lava and then being able to load up passengers, and then taking off was crazy. Think the writers were on mind altering drugs.
This was ultimately a “ Bad Trip”.
Maybe, Covid interfered between season 3 and 4 , and then season 4 became an afterthought.
Would not recommend, or just stop after season 3.
