Cheating?

We talked in class this week about how Hemingway, along with others, believe that everything Twain wrote after chapter 30 was cheating in terms of what a realism novel should be.  Although I agree that the novel had a very different feel to it during this section, I have a hard time calling it cheating.  Maybe it was Twain's intention all along to make it more of a fantasy novel towards the end.  Either way it was completely up to Twain how he wanted to write the story.  I do find it interesting however that he chose to go this direction with novel.  Going back to the first few chapters, it almost seems like a completely different book.  Maybe Twain's notice at the beginning of the novel was also an indication that he was going to take his readers in a variety of directions.  Perhaps he put it there to prepare us for the less realistic parts of the story and to tell us not to take it too seriously.  

Ok, was anyone else seriously annoyed with Tom and his idiotic plans?  I had such a hard time getting through the last couple chapters cause I just wanted to shake Tom and tell him his ideas were dumb and unnecessary.  I was also a little angry with Huck for just going along with it even though he knew they were terrible plans.  And poor Jim! I would've been so upset with Tom if I was Jim. As likable as Huck is, there are not a lot of good qualities in Tom.  For me at least, he is a hard character to put up with.  Is it bad that I was happy he got shot playing out his senseless plan?
