You need to have things that make your imagination go. If there is no science fiction we would all be boring with no imagination at all. No violence Science fiction is good only if there is no violence because it gives creative ideas to write stories and poems. It doesn't matter if it isn't true because it is your choice to believe it or not. It should not affect technical science because scientists know if it is possible or not.
Science fiction is enjoyable to read or watch for entertainment.
More exciting Science fiction gives people more interest in science. Science fiction is more exciting than normal science. Science fiction stretches your mind and makes you imagine about things that aren't possible. It's bad when people may believe they are true. Although it would not be possible to happen like Jurassic Park because the egg is frozen and the cells in the egg is already dead.
