(Minor spoilers)
I am a real fan of this franchise, even if know that Gou was not the best sequel, I am still like it because has the same vibes as the 2006 original show.
But when we talk about Sotsu I would really like to say the same, but no.
Satsu starts strong with the story of Rena, which was left out of Gou, but then we a lot recaps episodes with almost no new information about the main plot. Just some scenes about Satoko and how she got a gun. We also get tiny information about Eua's character, but nothing really relevant.
13 episodes after comes to the resolution of the main conflict in just 2 episodes and were the biggest disappointment. Higurashi was an anime about mystery and thriller, but the "final battle" is a "shounen final battle". 15 episodes for nothing. they just can put the last 2 episodes in Gou and we got almost the same anime and save money.
I was expecting some mind games between Rika and Satoko. Ultimate disappoint.
In other topics, the animation and sound are decent, but even the most outstanding production can't save this trash.
