I can´t believe that this is a drama that aired just last year and I never heard of it until a few days ago, probably if it had aired on a bigger television platform it would have had much more success but let's focus on what this series had instead of what it lacked.
Great storyline, I think the writer did a great job of making the story interesting without it being boring. Crime dramas, most of the time, tend to be a lot to diggest, the writer focuses on giving us as much information as he can, which makes the whole watching process really tiring as you´re trying to keep up with all the information you´re given taking all the enjoyability from it but that´s definitely not the case in "Kill it" in which the writer gives you time to enjoy the drama as well.
Casting, the actors were perfect for each role. While watching this drama, I never once thought that a certain actor was doing a bad job or was doing something out of character, they portrayed their characters' emotions and circumstances really well, which made the storyline more complete.
The number of episodes, this is where many series of 16 or 20 episodes go wrong, they stretch the storyline as much as they can and had filler scenes all over the place, so I´m really grateful that here, they stuck with 12 episodes, while it may not seem enough, it gave enough time for the story to develop really well, and without dozens of filler scenes in between.
Overall, if you want a quick yet intense crime drama with great acting that will always keep you on the edge of your seat, watch "Kill it".
