"13 Reasons Why" is undergoing some changes in Season 2 to help facilitate discussions between parents and teens about difficult topics like suicide, bullying, and sexual assault.

The teen drama became a cultural sensation for tackling those issues as it explored the circumstances surrounding the suicide of high schooler Hannah Baker (Katherine Langford). The show also received criticism for its graphic depiction of her death as well as framing the story around blaming people connected to her.

In a blog post, Netflix explained it had partnered with Northwestern University's Center on Media and Human Development on a global research study to determine "whether and how the series opened dialogue between teens and parents."

Some key findings: 71 percent of teens and young adults found the show relatable, and nearly three-quarters of teen and young adult viewers said the show made them feel more comfortable processing tough topics. More than half of teens reached out to someone to apologize for how they had treated them, and nearly three-quarters of teens said that they tried to be more considerate about how they treated others after watching the show.

Parents who participated in the study indicated they wanted more resources for discussions, so Netflix is adding new features to the show for Season 2, which is expected to stream later this year.

The first change is a custom intro featuring the cast at the start of every new season (the one for Season 2 can be watched below). There will also be a new after show featuring the actors, experts, and educators. And the site 13ReasonsWhy.Info will include even more guidance from mental health experts as well as a viewing guide.
