I'd been looking forward to this. Corpse Party is a horror video game series that's also spawned:
Corpse Party: Missing Footage (OVA) = 11 minutes
Corpse Party: Tortured Souls (OVA) = four half-hour episodes
Corpse Party (2015 live-action film)
Corpse Party: Book of Shadows (2016 live-action film)
Missing Footage is just a bunch of random scenes. No plot, no narrative. It starts with crying girls, tied up and stabbed to death. Everything after that, though, is harmless fluff with high school students. (Mind you, Yuuka gets in the bath with her brother.) My reaction at the end: "was that it?"
No problem, though. It's called "missing footage", after all. I started Tortured Souls... and could hardly see anything most of the time. Schoolgirls wander around in the dark. It's like a badly written radio play that hasn't realised it's audio-only. Squishy, creepy noises. Intensity. Is that a hanging? Possibly, but I'm guessing here. The series would have probably been good if I'd been able to follow it, but I couldn't, so I quit.
The non-horror introductory scenes are well lit, admittedly.
