Watching "TV"

(Note: There are probably random spoilers in here.  Not that it should matter, honestly.  I don't often find learning plot points about most things ruins them.  Good stories are made in the way they are told, not usually in what they are about.  But fair warning here just the same because who knows what I might say?)

I watch a lot of "TV."  But what I'm calling "TV" my kids would call "Movies."  They call everything on a screen a Movie.  Except for things they watch on particular YouTube Channels, but even odd things here and there on YouTube they call Movies.  (If you have half an hour the clip in that link is very funny.)  I'm starting to wonder if we need new terms in general.  Maybe "Features" for what I think of as movies, and "Serial Dramas/Comedies" for what I think of as television.

I want to say the main difference between movies and television has to do with telling a single, contained story, versus drawing one out in parts, possibly over years.  But there are still exceptions there, because, you know, Star Wars.  And I remember seeing the movie Shoah over the course of two nights when it came out, because its total running length on screen was over nine hours, and there are entire British television series that can be viewed in less time.  There are movies that are essentially parts of a series, such as the Up documentaries (the first one of those I saw in a theater was 28 Up as a child and I look forward to the next installment every seven years).  Star Trek straddles both worlds but tells its best stories on TV in my opinion.  TV allows characters and ideas to develop in ways movies don't have patience for.
