Some think it’s a bit too nuanced, but, by and large, audiences and critics liked “Chappaquiddick,’’ the docudrama about the fateful night nearly five decades ago when a car driven by then-Senator Ted Kennedy went off a bridge on Chappaquiddick, resulting in the death of Mary Jo Kopechne.

But Neil deGrasse Tyson, the celebrated author and astrophysicist who sees things through a different lens, has another complaint. In a tweet last week, Tyson pointed out an interesting factual error in the film.

“Chappaquiddick occurred just 2 days before the first lunar landing,’’ he tweeted. “So you’d think the Film producers would get the Moon right for July 18, 1969. Kennedy sees it full, but the actual phase was a 4-day old waxing crescent that set long before the midnight tragedy. I’m just saying.’’

Starring Jason Clarke as Kennedy and Kate Mara as Kopechne, “Chappaquiddick,’’ with a $34 million production budget, has done modest business, grossing just $17 million.
