There is so much we encounter in the world that is dysunctional, ugly, stupid, or just downright bad. But if you think about it, it's sometimes surprising that nuggets of gold can actually be found hidden under so many layers of muck. Even Really Bad Things do on occasion have redeeming qualities.
Take for instance the movie 'Revenge of the Nerds 2' - an insipid comedy if ever there was. It fared poorly in the box office and you're not likely to hear Ebert & Roper referencing the film as any sort of milestone while reviewing other movies. It did, however, have what I thought was one of the funniest themes and individual line ever. The character 'Booger' was a complete scumbag/slob who encounters a sort of scumbag/slob 'spiritual master' (who can belch louder than anyone). At one point he is dispensing slob wisdom and says "To truly hawk a lugey one must not draw phlegm from one's throat, rather, it must come from one's Soul". Didn't laugh at any other jokes in the entire film but that one moment represents the movie's one redemption.
Another example, the Edsel. Regarded as a lemon from a design perspective and a marketing disaster of the first magnitude by Ford. BUT isn't the idea of having a car that operates with lots of push-buttons kinda cool?
One last example, gas prices. Yes when they jumped they had a generally slowing effect on the world economy and created all sorts of hardship for folks who were not well-off to begin with BUT they did have the effect of causing us all to stop a moment, step back, get perspective, and begin serious discussion and consideration of the world's future and also to consider how our lifestyles fit into this. Gas prices have dropped considerably the last few weeks, but don't worry I'm pretty sure they'll be back up to previous levels not long after the Presidential election is over.
Any other examples of redemptive qualities that you can think of for things you would otherwise regard as Really Bad? Polyester fabric? Michael Jackson? Atonal music? Monster trucks? Mussolini? Regressive tax systems? The City of Buffalo?
