The last about two or three episodes of 13 Reasons Why were quite decent cuz they 1- Embraced the school drama aspect and not as much as on who killed who and 2- They focused less on Clay
I just finished the fourth season (I watched the other 3 on release, but I was just so burnt out from the series I only recently picked the last season up). For all its flaws, I think the conclusion was quite satisfying although bittersweet (Justin :( ).
