i usually watch the whole show. i'm just about to finish the deuce which is only 3 seasons but i've watched full runs of other long shows like 24 and Lost. i find it better to stay inside the one world instead of jumping from something prestige to a show that's completely different

i can understand people who can't do that though. it does get a little fatiguing sticking with the same characters for 50-100 hours and the writing also plays a huge part in the longevity of interest but it's still my preference
