There are very few shows that belong in the upper echelon of the sci-fi genre, but one of those projects has had a criminally low profile since the day it premiered in 2019. As can often be the case with Apple TV shows, the project is of an incredibly high quality but lacks the viewership it deserves. Thankfully, it has been continually renewed, and the arrival of its fifth season is imminent. If you start now, there's still plenty of time to catch up ahead of the Season 5 premiere.
