The 16-episode second season of The Gifted aired during the 2018/2019 TV season. It ended up being the series' final season, as it was canceled without getting a full season run. It is a bittersweet end because the season was very good, and the writers were clearly setting up a third season that would have taken the show in a different direction, but the show was canceled after the season aired. However, it provided a decent ending to the initial storyline that was the focus of season one.
This season can best be summed up by mutants vs. mutants vs. humans. One team of mutants consisted of the inner circle, formed after Lorna and Andy decided to go with the triplets and split from the mutant underground. Both groups faced a threat from a group of anti-mutant humans, eventually led by Jace after his dismissal from sentinel services, who are basically a group of vigilantes who hunt down mutants. Peter Gallagher (of The OC and Covert Affairs) comes in part-way through the season to play an anti-mutant television personality who stirs up trouble. In large part, the entire season is a metaphor for today's political climate.
Every episode provides a back story for each main character told through flashbacks. It is the main vehicle for character development this season. I will not give too much of the story away, but the crux of the season is about stopping an all-out war between mutants and humans.
The DVD set is a four-disc set. It is a basic MOD set with no extras of any kind and no subtitles. The set has 16 episodes, which can be played individually or in a play-all mode. So, the only reason to get this is if you bought season one on DVD and want it to have both seasons. Otherwise, there is no benefit that you will get with the DVDs versus streaming the show.
