In the Order of Worship/Service, what is essential?

I thought I'd throw this thought out into the light of day. In our various church backgrounds, what do you consider as essential in your Order of Worship and what parts are secondary (indifferent) or to say, may help and not harm a Worship Service?
What is the main reason you attend church?

I enjoyed your comment, nube!
What would you consider changing? How would that effect other people in that particular fellowship?
