This could just be an issue with my copy, but I really struggled with how loud every sound was. Every firework, crowd cheering, siren sound, scream, etc. was bass boosted as hell. Very overwhelming/overstimulating.
The v* happens at 1:20:26 and lasts about 10 seconds. It occurs directly after they walk into the home of the woman with the boat. No visual besides the pregnant woman bending over. The sound is realistic and gross.
