Are Hollywood Films Realistic?

I believe holly wood movies does not all capture facts right about true stories. Sometimes true stories can not always be completely interesting. Therefore in order to make the movies that are true stories more interesting, there may be certain aspect that  the creators add on in order to make it more indulging.  I agree that we can learn true things from realistic, popular films. Whether is be moral or just facts, I do believe we can learn from popular films especially film that have an inner deeper philosophical idea behind them.  I can trust Hollywood movies as a reliable source to an extent.
