Since you all know each episode is a different story, and its difficult to score the entire series. Few of the stories will blow your mind. Most of them are good. The third episode of Season 5 is very very bad and melodramatic. The First three seasons were very very good and would get a strong 9/10. Drops a bit at fourth season which to be honest is a 7.5/10. Overall this is a series that you must watch. Another good thing about it is that you can just pick any episode and start watching.
