Cloud Atlas the Movie may be one of those cases where the movie is better than the book. The back and forth through time is clear and poignant in the movie whereas in the book I was totally lost. The downside is the stories I liked in the book were cut down considerably for the movie, but it all still worked.
Growing up, I was *way* more into Star Wars than into Star Trek, which reflected my predilection towards fantasy over science fiction. But David Brin's essay in Salon in the wake of the debacle of "The Phantom Menace" is probably the turning point leading me to eventually repudiate Star Wars and embrace Star Trek.
