As for my favorite... I'll take the easy way and pick the heroine of my favorite sci-fi movie, Aliens. Yes, Ellen Ripley is just the kind of kick-ass heroine that I didn't imitate in Song, but the movie itself is a superlative example of blending characters, action, story, special effects and worldbuilding, and even science (in terms of the aliens' life cycle).
Whenever I watch sci-fi movies from the 80s, I marvel at how amazingly realistic Aliens looks by comparison. Hard to believe it came out almost a quarter-century ago (1986).
