I wouldn't run the whole script blindly. You will have to do more than one linear pass through the script to find and invert settings you later discover you don't like. I recommend one close readthrough, uncommenting or commenting things you do or don't like, and then a full run. I do recommend running the script after a careful edit. It will save you time.
