Never once as a child did I think Miss Piggy was sexy. Not once did I think she was worth Kermie's efforts. I still think she's, well, pigly. But I guess part of what drew me into the dramedy of the frog and his suitress was that tension, the lady whom everybody else thought was attractive but the man she fell for. Eventually, Kermit would always wimp out as Hollywood convention would dictate, but somehow you knew we were laughing with them, not at them.
I wonder how they would update the Muppets. I still cringe at aspects of Sesame Street that have changed over the years, especially the kiddy/Casio/Kenny G travesty that has become of the opening song. The song I grew up with, at the least, seems to have teeth in it by comparison. I wonder if it was the PC culture that caused that song to change so much. More likely it was the softer, kinder, gentler approach of a large monolithic purple dinosaur (Barney as political commentary? I could see that.). In any case the Muppets I grew up with and that you grew up with have long been abandoned by us. Like in the Talking Heads song, "This is not my beautiful house / this is not my beautiful wife / these are not my beloved Muppets."
Let the days go by... I eagerly anticipate the Muppets coming back, but with a bit of fearful trepidation, like the last installment of the Star Wars saga.
