Corona Extra

As one of the top selling beers worldwide, is Corona Extra a decent beer? I don't think so, it is certainly a fashionable beer, people seem to like it and people are certainly happy to purchase Corona Extra.

I really don't get why either a lime or lemon slice is jammed down the neck of the bottle. It certainly makes the beer taste nicer adding some tartness, but does any other beer producer require a citrus wedge to improve the drink? I know of no other beer served in such a manner and I can't say I much like the beer if a lemon or lime wedge isn't thrust down the neck.
