Movies Explained!

Is there any such website where one can go and get a full explanation of any movies? Such as.. what is a certain movie all about.. what did the movie try to convey and other questions.

Say for example, I don't understand the movie completely - Apocalypse Now! Where would I go to find out what the director wanted to show?

I may be naive, or plain stupid but there are some movies I would like to know what certain things meant.

If anyone know of such a website please let me know.

Thank you in advance.

A good place to start is www.imdb.com. Check out the sub-headings on the left, such as "external reviews", "trivia", "official sites" and "miscellaneous sites". Those should answer just about any question you have.
