I would imagine many people stop during this first act or during the last one when you can tell how everything is going to be tied together.

For people who don't like these type of movies, there are plenty of other 'films' (not movies) out there, that cater for the times when something popcorny isn't what you want.

With Red Notice, it's clear from the stills/trailer that it's a simple actioner, you are going to know if that's your thing even before you press play.

If the second I would say I’m very likely to turn off movies at 10 minutes in. That is the point where I realise that a movie is not what I imagined it to be, or that I’m not feeling like watching something after all. That being said maybe I’m the odd one out so I can’t say what masses of people actually do.
