The movie is as objectively factual as I think any portrayal of this incident possibly could be. It was as if the writers and producers set out to adapt the Wikipedia article on Chappaquiddick to the big screen as faithfully as possible. It is like "The Passion of Christ" in its historical detail. Although the acting and production quality were all top notch, I found the portrayal to be too generous to Ted Kennedy. He was projected as an abused son with a well meaning but weak moral conscience.
There were several flashback sequences offering a variety of interpretations. Only at the end were there two, less than a second each, glimpses of anything remotely sexual. The first was of a sympathetic Mary Jo Kopechne reaching out to caress Ted Kennedy's face and then one of her clothed upper body laying on the hood of his car. No mention was ever made of the actual police report of her missing panties.
Ted Kennedy was a sociopath who most likely left his young mistress to die a miserable death in a misguided attempt to save his own political career. He waited ten hours to report the incident while the diver who found her body still grasping the back seat in the remaining pocket of air estimated she could have been saved had Ted Kennedy reported the incident in the first three to four hours. The movie didn't explain this fact either. Despite the wailing of this New York Slimes writer, this movie goes easy on the memory of this monster.
In his book, Leo Damore mentions that the State Police placed a valid drivers license in his file. This was to cover up the fact that his was expired.
Did the movie show that? Also the diver flat out said that he could have saved her if he had been called immediately. Was that shown?
The answer to those questions will tell me whether or not to watch it.
