Batman v Vader
Since the production values on this fanmade film are better than all the science fiction films I saw in my youth, including FORBIDDEN PLANET, I would say that we live in the golden age of science fiction.
Skip to about 0.30 to see the action.
And this, of course, if my favorite type of science fiction, pure quill which pulp space opera of that kitchen-sink style that pits a 1930s Depression-era man of mystery against the psionic cyborg dark lord of the Sith.
