Do you find the characters on shows with science fiction elements dwell on religion more often than shows with a more realistic genres?

I cannot recall a science fiction show, movie, or story wherein the characters did not spend some time dealing with their own faith.

I very rarely watch a show or a movie of more mainstream genres where the characters even mention religion or declare their own faith out loud.

Am I selectively remembering this, or does something about science fiction necessitate religious discussion? Or is that authors of science fiction think about this topic more often than other writers?
