Jessica Jones tells the story of a hard-drinking, reckless private investigator (played by Krysten Ritter), who is broken in large part because of the season's big bad, Killgrave (played by David Tennant) who can control the minds of anyone who can hear him. It is hard to say too much about their backstory without giving too much about the season away, but the entire season revolves around Jessica trying to stop him. The show boasts a great supporting cast including (among others) Rachael Taylor, who plays Jessica's "sister," a former teen star with a rough past of her own; Carrie Ann Moss, who plays a high-powered attorney who Jessica sometimes helps and vice-versa, and later in the season Rosario Dawson, whose character is the glue that ties all the Netflix Marvel shows together. The series also introduces the character of Luke Cage (played by Mike Colter), who later gets his own show and provides some of his backstory.
As has been the case with the other Marvel shows on Netflix, it is much darker and grittier than the movies or the Agents of SHIELD show on ABC. Much of this is because of what they can get away with without censors, so there is more swearing and sex, but it also delves into darker topics and is much more violent. That said, there is not a ton of gore or nudity. It does get bloodier by the end of the season, however. It is not something that younger kids should be watching even though it is in the same superhero universe of the more kid-friendly movies.
The show looks great on blu-ray, as you would expect. The discs just have the episodes but no special features at all (much like the Daredevil release). Unlike the House of Cards releases, there is no behind-the-scenes material, deleted scenes, etc. That is the only thing that knocks the set down a star for me, the show itself is great. It does take a few episodes to set everything up to really see where the story is going. I cannot say everyone will like it, but if most people who are into these kinds of shows give it a chance, they will enjoy it.
