I found this anime because I'm a huge fan of the Corpse Party video games. Maybe the bar was set a little too high because I was not happy with the show.
I know they only got four episodes to do this long story in, but they could have done better. Everything felt extremely rushed. You didn't get to have a feel for the characters like you do in the game. There were a few side characters that only got about 10 seconds of screen time when they were actually important in the story.
When I got to the end, I was let down. I expected changes, but this was just awful. I hope in the future they can redo this, and make it longer. 4 Episodes is just not enough for the fantastic story of Corpse Party.
