I think ceremonies serve no purpose other than showing off to your friends and family. The vows themselves aren't even vows; if you haven't made the same vows and more a thousand times before you've gotten to the altar, then any words you say at that moment are hollow. Maybe some people like that kind of thing; to each his/her own. There are better ways of showing your love for someone than dressing up and parading yourself around on stage like some kind of performing monkey.
