If you are genuinely interested in the history of the region, the saddest part is that it's not 'sensationalized' as you put it, but the opposite--it's incredibly well-documented. Even released CIA documents confirm the coup and other actions. I don't see much disagreement between Wikipedia and what I wrote.
And Iranians, like Americans, differ in their opinions of government. There are nearly 100 million Iranians in country (and many more outside).
And of course if you read what I wrote, it's fairly clear why many Iranians didn't want a religious nationalist government, and many left over the past decades. Many of them didn't want the Shah or his Israel-trained brutal secret police, either, and many more didn't want the country's economy sold wholesale to the West (as it was).
