You may already know that Dangan Ronpa is the anime adaption of a video game by the same name.
You should also know it is the worse anime adaption of a game that was ever made.
Despite having a great story, it is impossible to realize how good it is or even enjoy it in the anime because the pacing is absolutely horrible. Everything happens too fast and nothing is explained, especially during investigations. A lot of important information is lost.
There is no character development, apart from things that are very important for the story. The lack of free times makes the characters bland.
The animation is a disaster, not even still images have good art. For something called "Dangan Ronpa: THE ANIMATION" there sure very few of it.
The only good thing about this adaption is the music. Why? Well the OST is the same one from the game (surprise!), and they actually did a good job with the ending. However I am not a fan of the changes they made to the opening song.
I am still watching this anime for the sole reason that I have already played the whole game beforehand, so I know the story. I'm using the anime as "extra footage" to watch some situations from the game "animated" (altough there's not much animation in this anyway).
Conclusion: Don't watch the anime, play the game. If you really want to watch it, do it after you've played the whole game. Please don't let the anime ruin a great story for you.
