Season 1 was so good.its screenplay, music, writing, acting all were upto the mark. Season 2 and 3 were average, it has so much flaws like irritating,unnecessary and unexplained character introduction and also dragging in story. Also it has some logic issues infact whole show has, but here, they were ehhhhhh? . In Season 4,feared at the start,but second half was like its going to be better ending and emotional seriously it has good ending and way more emotional than i thought. In last two episodes, i cried like baby by watching him and by imagining his smile in season 1 :'( Clay speech at the graduation feels like he is actually speaking to us. RIP one of the fav character!
