Overrated? Wouldn't someone have to like it or say that it is good for it to be overrated? Sure, people drink it, maybe even a lot, but I wouldn't say that it is a well regarded beer...
Not highly regarded by beer connoisseurs, true...but go to a supermarket (notably the two I normally patronise, the H-T in Pentagon Row and the Giant in Penrose Square) and, apart from the mass-market domestic lagers, Corona and Corona Light have more shelf space than any other brand. If it doesn't get a thumbs-up from knowledgeable beer drinkers, it does, sadly, win the battle of the marketplace.
[Corona Light...now
that is something I've never gotten up the nerve to try, and I just can't get my mind round it...I mean
regular Corona has no flavour...is it possible for a beer to have
negative flavour?]
