That is also a nice format. I would guess that it is just the subject matter that will hold you to the movie, movies, or series. If you are interested, the whole thing will hold your attention, if not, then you don’t watch.

I like a good mini-series, like Chernobyl. 3 normal sized movies and you're done.

Yes, that is true. 
They could have made LOTR into a 30 hour extravaganza had they wanted to.
Short pieces require more tight thinking and editing to get a story coherently told.
However, there is a place for either long form or short form stories.
Treatments of “Dune” have been long series form, short, one movie form and a two movie form. Yet I liked all o them

Netflix Movies vs. Series

I like that a series offers a lot more time to tell a proper story whereas a lot of movies seem to cut corners because they only have 2 hours. 

I like the short time commitment of just a movie but I also like the connection that I get with some TV series.
