Take a look at a blog called "Parchment and Pen," where you'll find a good piece of observational writing from C. Michael Patton, who made an ecclesiastical field trip to visit a couple of (quite) different churches.
The author is kind and generous, but also honest in his observations and evaluation. I think I would have been tempted to come across much more critically.
Read it, and let me know what YOU think.
...Wait, they had an elf who greeted the kids at the door?
