Is School 2013 worth watching?

I personally loved the show, and it is definitely one of my favourite dramas of all time. It has a great characters and a great story that deals with issues in the school system. And for your second question, in my opinion it takes probably about a couple of episodes for things to get going. 

its amazing my most rewatched drama ever ..definitely worth it ..but u will like it by ep 4 as u reach ep 7 it become addiction ,at least that was for me ..
