First off, You should watch Corpse Party: Missing Footage, That adds about 1 minute of backstory and 10 minutes of grunting, screaming, crying and brutal gore.
There really is little plot in this, I feel it could have been solved out in 2 episodes lasting 20 minutes each if that. It is interesting to see what happened, however, they never fully tell you why. You learn little bits and pieces and you need to put them together to figure it out.
Honestly if you want to waste 2 hours watching people get gored that's your business. I do not think this anime deserves this high of a score. writing more of a review on this is rather impossible because there is nothing, nothing you can critique more. Enjoy~
