How sad. This series started with some strong plot lines, potent characters, and attention to detail that was laudable. By the end it was one trite, predictable, superficial, weary plot contrivance after another. I particularly disliked the way a year's worth of story (because of the missing COVID-19 shooting schedule) was glossed over with a little exposition by the characters.

Everything was a little too convenient. Every discovery was a little too timely, every serendipitous moment just so. Like a too-sweet dish ruining a meal, the series was kinda ruined by the rush to get everything wrapped up by the end of the season. Ick.

Watch the first two seasons and just live with the mystery of what happened to the expedition rather than suffer the bitter disappointment of the last season. You'll be better off for it.
