All The President's Men

As this type of journalism or something, but for my broadcast journalism class.

Investigative? If you are suppose to watch the movie for the class, it is worth your time.

Maybe you should just watch the movie and see for yourself.
If you do it would be like a kind of journalist doing research (research) for a story
Is not that what you study?
do the job, if you're lazy, you will not get the job afterwards.
