Aw, I kinda hoped they both would survive, but when they started to go down those stairs I knew they weren't coming back up anymore. I really liked Shuichi so it was a shame seeing him go down like that. If he only had left right from the start..
Overall not the scariest thing out there, but surely creepy and messed up. I felt so bad for the snail people.. At least Mitsuo got out..? Probably. Although it's sad Kirie can never go back to find him like she promised.
And I'm not annoyed by the "unexplained" ending, I think we got quite good explanation even though some things were left unknown. I feel like most of the people complaining about it, didn't pay enough attention, or can't use their imagination.
I'll be definitely checking out more Junji Ito's work.
