No.

Consider the SciFi classic Dune. I consider it to be just barely SciFi, because there is a little science involved (just a little). The reality of living on a desert planet with little water, evaporator farming, suits that collect and reuse water are kind of science. But a giant sandworm is little different from a dragon--no science involved. The endearing quality of Dune is not it's science, but it's soap opera--it's interaction between people.

Now consider one of my all-time favorites: Encounter with Tiber. This also contains a soap opera (to be all things to all people, I guess) but it's much more. It's a tour de force of bunches of real technologies and schemes that have been dreamed up over the years that might be used in real interstellar travel. I don't think anyone has ever made a huge hoop of superconducting wire to ionize free hydrogen in space and use it to propel a spacecraft--but the system has been designed and is presented in the book. Excellent! Real science. Real engineering. Monsters are optional.
