A little bit of a Follies tie-in with my comment on this topic. Jane Houdyshell, who's in the cast, played Lisa Kron's mother in the play "Well." Lisa is frustrated at her mother's inability to make herself feel physically better from the chronic ailments that plague her. Lisa somehow overcame a chronic physical malady that she had in her adolescence, and so has little patience that her mom seems unable, (or is it unwilling?) to do the same. Her mother finally says to her, "LISA! Not everybody has the same resources as you."
So I think it's great that people who are prepared to skip the breaks in Nicholas Nickelby had the physical resources to do so -- or at least thought they did -- but everybody does not have the same body.
I think comparing a long movie to a lengthy intermission-less musical is somewhat foolish. For one thing, people get up and go to the rest room during movies fairly often once they go over the two hour mark. Also, movies are not the special occasion for most people going to a show is. Often, they kick off the special occasion with dinner and/or drinks before the show. Beer is, famously, the drink you don't buy, but rent. A large dinner out often gets things moving for people about 45 minutes after consumption. Secondly, getting up and slipping out to the restroom at a movie theater is in no way as disruptive as having to climb over cramped rows in a Broadway house, and it's rendered even more of a challenge when the seasons change and outerwear becomes bigger and bulkier.
Some people have inflammatory bowel disease. Some are cursed with small bladders. In other words, not everybody has the same resources as the camels who think if they can stay put for two and a half hours then EVERYBODY can. Everybody's different and it's not just complaints of the so-called "blue-hairs," who have just as much right to see a show about the distant past as anybody.
