Academic and speculative fears have little place in the cold, hard reality of a girl pants world. But I think this one is compelling enough to qualify.
My mother recently tried to make me watch Mamma Mia! -the movie based on the songs of 70's supergroup ABBA (sorry, I can't type a backwards "B"). I made it about 20 minutes, which is really saying something, since any sane person not filled to the brim with filial affection would run screaming after five. For the love of my angel Mother, I stayed 20 eternal minutes, even as the maleficent plan of the Great Satan--to write this movie, get it made, and then inhabit the body of my mother and force me to watch her enjoy it, unrolled before my mind's horrified eye. If I wasn't already her favorite son, this sacrifice alone cements my status.
Even so, while the abject horribleness of this abomination did hurt, and hurt bad, it is not the subject currently at hand. No, another fear, far more horrifying than this experience, has begun to materialize: Given the suckcess of movies like Mamma Mia! and her sister flick "Across the Universe" (exclamation point optional), it is not unlikely--indeed, it is extremely probable--that at some future time, some future movie making demon will create and distribute a musical based on THE MUSIC OF THE EAGLES.
