(POTENTIAL SPOILERS) I enjoyed Sprites immensely. Profound, moving, and technically excellent, Bogart chose the perfect source material for the scene in Kirk's eulogy of Spock. Beyond that, one cannot escape the many layered implications of Jim's budding self-awareness, along with Lesley's reexamination of what it means to be human. It's very difficult to create dynamic characters in a 15 minute short, but Bogart succeeds. Great film.
