I never understood the Coors mystique. I grew up in Georgia, and someone brought a case back from "out west" way back when, and after all the anticipation, it was the wateriest beer I've ever had. I must admit, I can't disagree with you.
Coors and Heineken would get my split-vote for most overrated beers.
In the interest of full disclosure, I should point out that I can't drink beer (or any other alcoholic beverage) any more due to the medication I'm on. So I can't even have my beloved Moosehead...
