Fun vs Serious

This is the conundrum: should wedding photography attempt to create the most serious imagery during someone's special day, or do people prefer more lighthearted imagery?  I am of the opinion that good wedding photography requires a mix of both.  A wedding gallery devoid of lighthearted imagery just doesn't tend to accurately portrait the exciting and fun atmosphere which most wedding attendants tend to experience.  When you look back on the limited imagery from your special day you will obviously want to see some photos of you and your lover in a serious embrace, but wouldn't you also like to smile because of the silly, lighthearted behavior of the other people that you wanted to include on your special day?  Food for thought... Here in the Southwest and Durango areas I have found that most people are keen on letting loose on their wedding day.
