That's not the problem. The problem is the complete lack of anything even approaching horror.
Higurashi starts with people getting bludgeoned to death with a baseball bat. It ends with soldiers getting bowled over by log traps Benny Hill style.
Fuck it, we have that dude yelling about how "These are solid slugs, they're all totally scary and shit." How is it that people with knives means everybody dies horribly, but as soon as we hit "pitched gunfight" suddenly everyone has plot armour out the fucking wazoo?! Not to mention "Lulz, I actually have loads of experience firing AKs". What the shitting fuck?
