I'll try to keep it spoiler free for all of you. (After the edit there will be some spoilers) And this show is 6.5, not 6 nor a 7.

First of all - Almost no "physical action", no explosions or guns or cool fighting scenes.

Now for the juice- The show took existing stereotypes, or as I like to call them, "templates" and inserted them perfectly into the show. At first glance, we see the templates as hollow and shallow - Only as templates. But as the story progresses, or more like the Main Character (Clay) progress, the hollowness and gaps in said templates are filled. Which is refreshing. I never thought I'd find such templates, stereotypes, interesting and insightful.

The next thing, that really kept me tied to the chair (I finished the show IN ONE SITTING) was the politics. So much politics between the "wrongdoers". I loved that. It felt so real. I will not expand on it much, since I'll have to give out spoilers, so watch for yourself for this bit.

And my last praise - The relatability. Not only I could relate to Hannah, I could also relate to Clay and even some of the support/"wrongdoers". It started 'black and white' kinda show, but as the hollowness was filled, the more Grey it became and relatable. (Yet not Grey enough to cover their guilt, but it's just my opinion).

Clay. I want to expand about why I disliked him (at first, almost to the end of the show), but you'll have to watch for yourself. I don't wanna spoil.

EDIT:

Now, after some sleep and rethinking, I'm editing my review. Honestly, there are so many problems I forgot to mention...

1. Many characters don't get development or exploration. In other words, despite filling SOME gaps in the hollowness of the characters, they don't truly break them out of their stereotype.

2. Continuity problem? (SPOILERS!) - They have formed that sort of narrative or agenda that "Hanna's tapes are always true", yet the tape about Zach isn't 100% true and they just let it slide? Isn't it supposed to bring up doubts even if only 95% is true? (Hannah said he threw her letter, yet he shows said letter to Clay)

3. THE MAIN CHARACTER. I can't stress it enough.

4. (SPOILERS ABOUT THE ENDING!!) The ending felt weaker than it should have. I felt as if they weren't focusing enough on Hanna's inner world as much as they should - Even visually. As in I think they should have "shown" her inner world through metaphors, or seeing the world through her effed up mind, etc etc.
