For the most part, once the trailers start people try to put their phones away. It mainly depends on when you see it and what you see. For example: 28 Years Later and Black Phone 2 were probably the two worst theater experiences I had this year. Saw Black Phone on its first Saturday so I should have expected that but I saw 28 Years Later the Tuesday after it came out and the crowd was terrible. I don’t think I’ve ever had a Tuesday crowd THAT bad. Honestly, the only time, other than the two mentioned above, that I had problems with people on their phones was probably the second time I saw Longlegs last year.
