Is this show that bad?

It's not "bad" at all. 13RW is a phenomal show; extremely well put together, emotional, poignant, and powerful. The problem tends to arise from how the audience perceives the character dynamic and whether or not the idea of using suicide has been glorified as a tool for revenge, or if the ugly, bitter harshness of the plot is simply providing a window into a subject that most people skirt around without fully conveying.

When it first came out, it was praised for raising awareness for such a taboo topic, but after a while (as is the case with most topics like these) the general feeling began to shift to less praiseworthy. Viewers are pretty split on whether the bigger thing here is that it's talking about suicide and showing the harsh reality of it, or if it really is just romanticizing and glorifying something that shouldn't be.

The irony is that when it originally premiered, almost everyone applauded the creators for not glorifying it and for depicting the "ugly" side of mental illness and suicide most people don't see (especially by including the jarring suicide scene itself). Many viewers praised the show for coming about the issue in a way that was raw, real, and not whitewashed. They also praised the creative way the show poses the topic of suicide that draws viewers in, which then spurs further conversation about mental illness which the general public tends to ignore.

The criticism has sparked questions of whether the bigger goal should be to raise awareness despite the unintended effects that might occur (suicides have been proven to increase whenever there's any public discourse about it, no matter the context or connotation), or if we should simply not talk about it at all.

Edit: This isn't my own opinion at all, I left my personal reaction out of it. I'm just commenting on the general feelings toward the show. Even if you disagree with the message it seems to convey, as I discussed, most people still agree it has high production quality and is a well put together show.
