on the other hand, Hollywood teaches people about history, and what they teach is sometimes big time Wrong!
Pocahontas (The Disney cartoon) is an example.  You look at her and you have to think... "Wow, she looks pretty buff for a 12 year old" which is how old she was when the historical event took place.  In the direct fo vid sequel, she's shown back on Europe, but they don't show her as a slave, who died of TB at age 28..... wouldn't make a good movie for the kiddlioes.
Hollywood is an entertainment machine, pure and simple.  Truth doesn't pay the bills.  If you want truth, see An Inconvinient Truth.  If truth is not that important to you, the machine will deliver to you what you want.  If you want entertainment with a hint of truth, check out the Indies, for they have nothing to lose, and much to gain.
