>>not just the usual slack-jawed movie audience<<
I know you didn’t mean that to sound as elitist as it did.
Not elitist, just factual.
One doesn’t have to be slack-jawed to enjoy “John Carter”- It’s a good movie for roday’s Hollywood.
But one does have to be slack-jawed if one saw it because of the marketing.
(May be a little ‘ageism’- movies are marketed to kids.)
