Do you prefer movies or a television series?

A few months ago, I had a discussion with a friend about which we preferred: movies or television series. He insisted that movies were better, and while he didn't say it, I have heard the argument that years later, we remember movie lines and scenes more than we recall the same from a series. There’s something that stays with you, much like a memory from your own life.

I tend to disagree because I feel like it takes time to warm up to characters. But then again, I prefer stories that are character-driven. A movie just doesn't do it for me. I'm not still thinking about most movies once I finish watching them, whereas I often will when it's a show I've been watching for a season or two. I'm assuming that the actors and writers for that specific show learn more about their characters and watch them evolve over time, similar to what I've always discovered when writing a book series. There are many layers, and some are removed faster than others. 

I've always had a difficult time writing one, standalone book that doesn't connect with others. Without getting into the full list of my books, I will say that the first four were couples, whereas everything after was part of my Hernandez series. Even Different Shades of the Same Color had a brief overlap that would drift into the series (that wasn't meant to be a series). It's kind of to the point that I assume that it's just not in me to write a book that's not at least a part of a couple, if not a series. It would just feel weird, and there's always so much story to tell. It's difficult to bluntly end it in one book. 

So, do you prefer watching a movie or streaming a series? Would you rather have a standalone book or one that leads to another....and another......
