Well-said. Speaking as someone on the authorial end of that particular issue, I agree with how the criticisms (and the defenses) should be phrased, and speaking as someone on the reader/viewer end, I try to approach it that way. I once had a lengthy debate with a friend about why I considered the factual errors at the beginning of the first X-Files movie to be a problem; she could not seem to understand why getting the mundane details of Texas wrong undermined the story's central schtick, i.e. the conspiracy-theory sense that all this weird stuff could be true. She didn't see why I should have that problem -- but at least we were having a debate about the right thing.
