You Say Custom Field Formatter I Say Template Preprocess Field

I must admit that in all the time I've spend developing Drupal 7 modules, I've never quite fully understood render arrays. Oh, I understand that it's basically an array of stuff with some objects mixed in for chaos and I've used preprocess functions to change some of the array adding custom functionality prior to it being rendered in the DOM. But, when it really came down to brass tax, I sort of always felt as if I were "hacking" it a little. Almost like I thought there was some Drupal API call that I was missing to get at the values, set custom values, etc.
