I disagree. I was incredibly saddened watching this movie.
I cried on more than one occasion. I wasn't bullied in high school. I had a couple of girls that I wasn't friends with, but we also didn't bully each other, we just didn't like each other and had harsh words with one another. I saw bullying. I felt bad for those being bullied. I never said anything to stand up for them. I wish I had the courage then, that I have now.

I can see how Hannah Baker felt the way she did. A girl at that age, going thru the things she did, you don't have to be mentally ill to commit suicide. She was at wit's end and she tried battling through it. What happened on tape 12 (Bryce), if you're not prepared for it as Hannah was not, I could feel her distress and could understand why she did what she did. She went to her counselor, her 'one last chance', and she didn't get the answers she wanted. You don't need to just be bullied, as you mentioned, to consider suicide. Consider what she went through. The suicide wasn't vengeance, the cassette tapes were.
The movie doesn't glorify suicide. How you can view it in that light has me baffled.
I also don't think the message is "suicide is an option." It's saying you don't know what goes on in the life of a kid and as a last resort, when they think there are no other options, suicide is a possibility.
The world is a f'd up place and it's harder on kids these days. I thought the pressure on me was great, but it's much harder on them now. With GPA's, Sports, striving for scholarships......The pressures weigh on them massively.
