Blunder The Dome

There really isn't much to say except WHY???  Under The Dome is probably going to be a decent mini-series, unfortunately it's basically a completely new story which bears almost no resemblance to the story in what I considered to be an excellent book.  We waited, for almost a year from the time it was announced, barely able to contain our excitement.  I read the book again, for the third time, and raced to finish it right before the TV version started.  I certainly don't expect the mini-series to be a word for word repetition of the book, I've been good with slight variances in other TV productions, especially Stephen King's.  This one, however, seems determined to change absolutely everything about the book from character personalities, character names, characters inside/outside the dome, communication through the dome, who's on the good side/bad side, the plot in general, I could keep going on about what's different and there have only been two episodes so far!  I was looking forward to seeing a movie quality version of the events I read, not a completely different story.  I'm sure it's going to be worth watching, since King himself is involved (at least credited as a producer of the show) and the die-hard purists are eventually going to get used to it.  I just keep coming back to WHY?
