"Why would you not want to read the entire story the author intended?"
Although I respect your snooty reply, The Stand was quite an excellent read before the Uncut version was released.
It's all about the story, I'm not really sure The Kid and Frannie's fight with her mom makes the story better but they are a nice addition. The core of story is there regardless but if you read the cut first you have something to look forward to when you read it again.
Also, the Cut version takes place in the 70s when King wrote it rather then the Uncut which had been updated. I think that's pretty cool too.
