If you want to get into Crime Dramas then this is where to start. The actors and actresses are great and the pace of the drama is just right. It's a shame that they had to recast the character of Choi Ja-hye (main prosecutor) in the middle of the series since you do get accustomed to her acting and dry humor.

Characters that stood out was of course Choi Ja-hye (Go Hyun-jung ---> Park Jin-hee) for her dry humor and sarcasm, but Kim Hak-Beom (Bong Tae-gyu) was on a new level of asshole that really made you hate the character; in a good way. In addition, Geum Na-ra (Jung Eun-chae) might seem like a meek housewife at first, however she gets better as the episodes progress that you end up cheering for her later on. The story is definitely violent so make sure to keep that in mind, but other than that it's a 100% recommended series of "who killed who". Watching the characters dig themselves deeper into their own graves as they try to cover up past crimes and current accusations makes "Return" the more enjoyable.
