I’ve never had trouble staying engaged with something I actually like and want to do. I will fall asleep if I don’t have my narcolepsy meds and I’m trying to do something I’m not truly interested in, yet can binge watch something I’m truly hooked on, into the wee hours, even without the meds.

My advice, start paying more attention to the things you are interested in and stop trying to be interested in things once you realize it. There’s no such thing as superiority of any entertainment or hobby over another, yet so many people shit all over themselves because they get it in their head that their interests are somehow wrong. Not liking something that everyone else does is fine, liking something no one else does is fine. Strive to be you, if you can’t focus on any movies you’re probably not watching movies you’re interested in. Maybe you aren’t interested in any movies at all, plenty of people just don’t get poems, paintings, music, literature, beer, wine, shoe culture, car culture…

Neurotypicals have the ability to be at peace with being bored, so much so that it’s called a disorder when someone can’t sit still and suck it up when the shit being served is just not interesting (to them). You literally have to smoke weed to attain that same level of apathy.
