Batman dies. But he dies early in this film, so that isn't a spoiler. This is one of those "think piece sci-fi" films from the sixties and seventies. It's sort of a sister piece to films like "Silent Running", "The Andromeda Strain", and a few others that go more into psychology than action. Still, there is action, or at least the semblance of action due to smart writing and directing. An astronaut finds himself alone on Mars after Batman dies. Okay, it isn't Batman, but it is Adam West. We're wondering if he is imagining the strange things going on, or if they're real. And there are strange things happening. And those "strange things" get wilder and wilder and more sinister, but is this a dying man's last dream? Or is it real? We're left with believing it is real.
