The story is set in an ultra modern academy where the "students" are forced to abide a set of rules that explain the situation they are in. One bad step and death will follow. From that point of view it is not unique, take for example SAW. It shares some details with Danganronpa, but SAW covers everything Danganronpa has except for the protagonists comeback that is generally specific to anime.
Artwork is not something that will impress you but I will say this, the characters designs are unprecedented. You can summarize artwork by its non excessive use of colors and lighting and by the pink blood that I would say was used as a form of censor but you would find that hard to believe because of its age rating.
One particular aspect I enjoyed about this anime is the fact that each character is unique with his pros and cons and that fact is indirectly stated in the first episode.
Also the level of predictability is extremely low, so from this point of view it is like a stream of cold water in an arid desert.
In spite of my seemingly pessimistic words from above I have enjoyed watching this anime because of the detective thinking that puts facts head to head in order to assemble the truth. It is one of the things I like doing. So if you share my taste in this matter I can assure you that Danganronpa is a worthwhile anime that creates a quality enjoyment level.
