I can't think of any film examples at the moment, but anything where the plot can be instantly resolved with "the characters have cell phones". Particularly anything where the plot revolves around people trying to find each other, being lost without a map, etc. Maybe that's more of a sitcom standard than one in film (Home Alone, perhaps?), but the concept of not simply being able to get in touch with a friend, or access the internet at a moment's notice is pretty un-relatable for many people these days, and that's only likely to become more and more true.
Re: Titanic - actually I suspect Titanic will hold up fairly well, if for nothing else what it did well (detail, ambiance) can't really be obsoleted. There are probably scenes where special effects may get a bit dated, but those aren't the "wow" moments for history buffs. Sure, the romance plot was sort of schlocky, and there's a plot hole or two, but I think audiences in the future will still have something to enjoy in it. I think that the special-effects-laden blockbusters are more likely to suffer.
Except for Independence Day. I was muttering about how awful it was the second I walked out of the theater... ugh
. For me, it can't really lose over time what it never had.
it's more about songs, colours and the story.
