For everyone in this thread: there is a “parent’s guide” section for every movie on IMDB that describes the objectionable scenes in every category. Spoilers are hidden, but if you’re going to watch a movie with sensitive people, then it is worth putting up with spoilers to know the extent of the awkwardness that awaits.
Example for The Lighthouse (with warnings about what OP posted): https://m.imdb.com/title/tt7984734/parentalguide/nudity
Certainly not an over reaction. If an app sends me an uninvited notification then it gets uninstalled and black listed immediately. Even with apps I use regularly, the notifications are blocked most of the day. People undervalue their attention, and phone notifications are trying to steal your attention. Block it all. Even messaging and email apps can be blocked. I’m pretty sure I’m going to check my phone in a maximum of the next 60 min and a message can wait till I’m ready to look at my phone at my convenience.
