People who thinks it's trash, most likely is because that only watched the first season, which this page shows. You have to watch the complete series in order to understand the plot. EVERY THING WILL MAKES SENSE!!! PLEASE WATCH IT!!!
-It's call Higurashi No Naku Koro Ni Kai.-
I won't write any specific about the plot because you can really understands its beauty after watching it. At least, I think its epic. One of the best wrotten, comparable with Steins;Gate. The music and other aspects are also good.
IT SHOULDN'T FAIL YOU.
