I heard about Akame ga Kill! in an anime in 2014 review. Labeled "the edgiest anime ever", the show had my curiosity.
The show is extremely dark and sad while having comedic moments and lighthearted fun. These themes aren't exactly well balanced and some may have trouble taking the who serious after it turns from extremely light to extreme dark. This is really the show's only major flaw.
The best feature of Akame ga Kill! has to be the characters. A wide variety of characters is presented. Each character, protagonist or antagonist, is giving a healthy amount of development and each is easily enjoyable. No antagonist is "too evil" and mostly of them are in the moral grey area. Most characters are given special powers. There is a decent amount of balance in powers, but some are weak while others could be considered overpowered.
The action sequences are masterfully done and simply beautiful and progressively get better as the show goes on. Romance is mildly touched on, but certainly not a major theme. The plot and the setting is great. The setting matches the plot and characters well. The pace of the show speeds up as the show progresses which some might welcome while others might not.
The show's imbalance might not agree with some, but the show is certainly worth the view. Prepare for dark and violent themes, extremely sad times, and a good helping of your typical comedic anime moments.
