I would have to agree, I taste more corn than rice. try comparing to bud you'll see what I mean.
I was talking to a brew master once, and he was telling me that American light's are a more difficult style because you do not have the strong flavors that can actually cover up a brew that is not perfect. in other words, if you do a good American lager, that would be something to brag about. I personally never have because if I’m putting in the effort I’m going to brew something that satisfies my hop addiction, but kudos to you if you pull it off!
concerning the wonderful comments about Pabst...
compare a Cadillac to a Kia, the caddie will win. compare PBR to DFH 90 IIPA, DFH will win, not a fair comparison IMHO. If you take Pabst Blue Ribbon for what it is, A macro American lager you might realize that it is a great beer within it's own league. compare PBR to any other American macro... besides, it still wins awards

(GABF '06 - gold in American-style lager to name one out of many)
I personally love all types of beer and PBR happens to be my favorite American macro. Yes, I keep a keg of PBR on tap (saves on wasted beer when people don’t like my DIPA) and I also collect Pabst antiques.
Just a suggestion, do a blind taste test within the same category. if you don't like this style that fine because then it's a matter of personal taste, but if you are flaming this beer because of the price tag, some stigmata or because you drank this beer when you where in college or better yet high skool, there is a really good chance you don't know what you're talking about. I on occasion have judged a person on their personal tastes based off their macro American choice. you say bud or Coors, you get my homebrew sake, you say PBR, you get the good stuff
CHEERS!!!
