"A big part of the job is looking for the worst in people. Turns out, I excel at that." The first line of the trailer for the new Marvel series "Jessica Jones" could not possibly be more telling about its titular superheroine.

On Oct. 23, Netflix released its first official trailer for "Jessica Jones." Starring Krysten Ritter, David Tennant, and Mike Coulter, "Jessica Jones" is a major landmark not only for Marvel but for television in general. Though ABC's "Agent Carter" was the first Marvel TV show to center its focus on a titular female character, Jessica Jones is officially Marvel's first female superhero to star in her own show.

Given that only 12 percent of clear protagonists, and 29 percent of major characters in film and television are women, "Jessica Jones" is a big freaking deal. She's busting through the ranks of male-fronted or ensemble superhero shows like "Arrow," "The Flash," "Agents of S.H.I.E.L.D." and "Daredevil."

CBS's "Supergirl" is the first female superhero to grace network television, airing on Oct. 26 of this year, but the two characters could not be more fundamentally different, and that is perhaps the most important distinction to make. While "Supergirl" offers the optimistic, traditional sense of a superhero, which is in no way a bad thing, "Jessica Jones" gives off a much more disturbing vibe.

You may remember when Netflix released "Daredevil," a dark, gritty show set in Hell's Kitchen, New York City starring Charlie Cox. If the synopsis for "Jessica Jones" is anything to go off of, it appears it will be much of the same.

Jones, a private detective, also in Hell's Kitchen like Daredevil, attempts to rebuild her personal life after her days as a superhero ended in tragedy. Self-loathing and PTSD are only some of the demons she ends up battling as she comes back into contact with the show's terrifying villain, Tennant's Zebediah Kilgrave.

The implications of "Jessica Jones" and its similarity to "Daredevil" are astronomical. Though "Daredevil" has significantly more gore suggested in its trailer, "Jessica Jones" has the feel of a psychological thriller or noir. Spoiler-free reviews of the pilot episode, which was shown at New York City Comic Con, indicate that the series is shameless, dark and disturbing.

Jones might not be the kind of woman people will want their children to look up to, but that doesn't mean she's not important. The "Strong Female Character" is defined, at the most basic level, as a woman with her own agenda, identity and story purpose. Oftentimes, however, this character becomes stereotypical and cartoonish, made useless after her first introductory scene.

In the assorted teasers that have been released over the past few weeks, as well as in the actual trailer, we can see that Jones drinks, brawls and struggles. She's not a caricature of a woman. She's allowed to be human, to be extraordinarily flawed, to be afraid.

She's allowed to be weak.

It is not a revolutionary idea, that women can be "Strong Female Characters" and still have breakdowns and troubles and moments of pure, unadulterated fear. That being said, to some, it is revolutionary, which makes "Jessica Jones" that much more powerful.

Based on images and information released over the past year, it is also interesting to note that Jones is surrounded by a support system made up of mostly women. Rachael Taylor and Carrie-Ann Moss play two of Jones' closest companions, and Rosario Dawson, who played Claire Temple a.k.a. Night Nurse on "Daredevil," has been confirmed to appear as well.

Supergirl is an ideal, a woman we all wish we could be, because she makes being a superhero look fun and cool and, well, heroic. She's more important to girls than you could possibly imagine. One woman wrote on her blog that her disillusioned sixteen-year-old shouted, "THERE’S HOPE FOR WOMEN IN A MALE-DOMINATED NERDVERSE!" upon finding out that Supergirl was, in fact, getting her own show.

Jones, though, is far from an ideal. She's not exactly a role model - foul mouthed, X-rated. She's part of an entirely different world and she's an entirely different woman. While Supergirl is a superhero coming into her own and still discovering her powers and what she can do, Jones knows exactly what she can do - and more importantly, what she can't.

Both shows are equally important. They're not competing and trying to be better than each other. What matters, in the end, is that there are two female superheroes debuting in the television world this year.

All episodes of Marvel's "Jessica Jones" will air on Netflix on Nov. 20, 2015.
