Efficient, nasty action scenes can't overcome mostly bland characterizations and a half-baked story.
... and channels roles from the entire career of James Earl Jones. That's the premise of this very funny short, "Vader Sessions," from Akjak Moving Pictures, in which the Imperial Villain speaks in Jones' voice through sound clips from "The Great White Hope" to "Clear and Present Danger" to "A Family Thing." (I kept waiting for him to announce: "This... is CNN.") I know: Is it possible for yet another "Star Wars" parody to be funny? I think these guys have demonstrated that it is. I'd love to know the sources of all the dialog used -- so feel free to post a comment with whatever you recognize.
