I'm surprised to see so many well known main stream beers being posted as the "worse" beer someone has ever had.
It seems that it is almost required to list a macro brew for it to be bad.
BMC, Lonestar, Corona, etc. are not THAT bad.
Maybe its just living in a country with a very very very limited beer selection (Budweiser, Heineken, Stella, Brahama and Quilmes) makes me appreciate these "bad" beers.
I can always drink a BMC and be satisfied and enjoy it, where as I have had a few micros that, after one sip, I had to pour it down the drain (Otro Mundo Golden Ale, Antares Kolsch, Barba Roja)
