Note: this is a mostly spoiler-free review of The 100: Season 4, which is currently available on Netflix in the US (and will hit DVD and Blu-ray on July 18th). I’ll discuss basic character and plot details, and provide a proper spoiler warning for some brief, most specific discussion at the end of the review.
The 100’s third season was a rocky one, to say the least. I don’t think it was nearly as disastrous overall as some — as terribly handled and impossible to overlook as the circumstances of Lexa’s death were — but there were multiple examples of clumsy storytelling, even as the show still had a lot of powerful and effective elements at work as well.
Still, the perception for many was that Season 4 needed to get the show back on track. And on that score, it did very well, delivering a year that had some trouble spots along the way, but was built on a strong spine, grew to a crescendo as it continued, and was capped off by some of the best material yet for The 100.
