Castro liked Stone’s films, so he gave him unprecedented access and freedom to do a documentary. Backlash forced him to go back and reshoot, also with Castro’s approval.
It’s certainly reasonable that some people are skeptical or critical of Stone’s decision to do this, but I don’t think it supports the idea of Stone being supportive of Communism or similar ideologies.
Stone may have some insights into Cuba others don’t have.
It’s like Charles Lindbergh gained the Germans trust, to the point that he gained valuable intel on their Luftwaffe that he passed to the government.
Stone’s lefist statements since his Cuban vacations lend no credence to your conclusions. All Stone and every other celebrity that did this was validate and strengthen Castro’s regimes hold on the Cuban people.
I hope this “buddying” up to Marxists such as Stone & RFK, Jr is not a continuation of Trump’s silly fascination with celebrities. Such a thing will not end well.
