Crying is definitely good for you. It has always made me feel better even though it can be difficult sometimes.

I didn't cry during the movie Hachiko although I really do like that movie.

I also really liked Smallville even though I have to say the later seasons when they switched writers were significantly better than the earlier ones in my opinion.

A lot of people walk around with their emotions bottled up because we are told that it's not a good idea to let anyone see who we really are.

This is an incredibly unhealthy way to live though. You must let your emotions out so that they don't destroy you. There is no better feeling than crying when something terrible happens...... because otherwise that emotion is going to come up at a later time and it's not going to be as easy to deal with at that point.
