I am so late to watch the second season of the series. Mostly Beacuse I heard mixed reviews and don't want to spoil the experience it give me in first season.
But, I have thoroughly enjoyed the each episode. Its quite interesting to know about each ones relationship with Hannah baker through their perspective.

With clay Jenson, we too surprise to know about the Zack and Hannah relationship. It's a bit sad about how cloe depends on Bryce. Jessica suffers alot to confess about what happend to her.

But as coming to near we understand every one is good at heart but taking decisions and choices at certain situations make the difference. That's what happened in Hannah case too.
Learning about why tony kept tapes secret makes sense. The actors played the characters very well. The screenplay is one thing that is succeeded to make show fantastic.
Although it's dispointing that bakers didn't got the justice they fought for but we also completely blame the school for its nature. Hannah kept silent about her problems most of the time and the management could have done more to protect her from suicidal thoughts.

I felt happy how Kevin portar was took the charge in his court and produced his side on testify. He even went to Justin floeny house to check on him to get him back to school.

Second season interesting from the beginning and it gives you more than what you expect in each episode. This is really good for who loved the characters of the series.
The great thing is clay's family adopts Justin. After all the traumatic events it's a heartwarming thing to see.

Tyler's episode is more horrible than tragic. I expect the third season will start form here. As per the news Katherine long ford (Hanna baker) will not be there in it. The teaser type of clip was released on YouTube and it's shows lunch pack in someone's locker. Nothing can be interpreted from that more with my knowledge.
I am waiting to meet all the characters again from the series in its third season.
