You watch movies to dissect their meanings, others watch movies to escape reality for a bit.
The dissecting of media (which i do a lot) isn't something i choose - it comes pretty automatically with media literacy. As soon as you develop the skills needed to analyze subtext and themes, and start to take a critical stance regarding video content, you can't really switch it off outside of getting wasted.
So i'd say the difference is simply in media literacy (and more broadly, general education) and level of cognitive impairment.
