I beg to differ. Med school admissions can often be a crap shoot, and you never know what an admissions committee member might like in your file. There are more than enough applicants with the requisite volunteering, good stats, and good LORs. Anything that can make you stand out to the adcom is a good thing.
I have a good GPA, a decent MCAT score, a normal amount of clinical exposure and some research experience... really nothing that spectacular. I wrote my entire personal statement about my experiences performing (since I've been doing that my entire life and have only wanted to pursue medicine for the past ~3 years), how I "found" medicine, and how these things will serve me in my future career as a physician. Sure it was a bit of a calculated risk, but I've ended up with awesome interviews and some great acceptances, and I attribute this solely to my PS. One of my interviewers told me that he was "dazzled by my essay" and he had "never read a PS like mine." I'm not trying to gloat, but I'm just trying to show that if you present yourself and your unique experiences in a positive and different way, you'll stand out from the masses and the admissions committee will see the interesting and multi-talented individual that you are.
EDIT: I also wanted to add that it's imperative to tie these unique ECs into your education and career as a future physician. Without tying your experiences into your passion for medicine, it will appear as if you're not serious about medicine or aren't sure what you want to do with your life.
