J K Rowling even created her own version of elves. Tolkien was among those authors who depicted elves as beautiful tall people with pointy ears and silky hair, but Rowling chose to depict them as ugly little things who treat themselves badly and even sadistically, but she still kept the definition of the word 'elf': a species which is diffirent from our own.
But Stephenie Meyer's Twilight and the rules which she set... oh no, oh no!
First, there is nothing wrong as I said, of making your own version of vampires but really, Stephenie Meyrs vampires not only suck blood, they just suck!:D It's not that she wrote that vampires sparkle in the sun but the idea of a sparkling vampire is just dumb. She hasn't made vampires scary and neither did she make them interesting. They can see into the future, they have super speed (a super speed which is so super which takes the Volturi two months to get to America when it only took Bella two days to get from Italy to her town by commercial transport!), they are absoloutely beautiful, so beautiful that even their breath is beautiful...:eek: and they have super strength. So, Meyers vampires are practically invincible, which makes them too perfect and so makes them uninteresting.
But if you created a fantasy world, goodness gracious man, then follow the rules which you set. We all know of the plot holes which Twilight contains, whether it be in the illogical decisions which it's characters make or in breaking of the rules which Meyer set, so I'm not going to mention them. But Deathly Hallows contains plot holes, not only in some illogical decisions which the characters make, but in the breaking of the rules which Rowling herself set. I'm going to list a few of these here:
-The invisibility cloak which Harry owns is one of the Deathly Hallows and is said as having impenetrable concealement of the wearer 'no matter what spells are cast at it.' Yet, Mad eye Moody's magic eye could see through Harry's cloak in book four and I think it used magic to work. Also, even though Xenophilius Lovegood never said it and I'm not saying that it necessarily should but, don't you think that since the deathly hallows make the possessor the master of death, the invisibilty should be a shield which protects you against spells? Even Fred and George invented clothes which protect the wearer from spells and hexes, why shouldn't the infallible invisibility cloak too? In the series, the cloak doesn't protect Harry from spells, because in book six, he gets hit twice by a spell while under the cloak: by Draco when he was spying on him and by Dumbledore when they got back from the cave.
-What about this ownership thing of the Elder Wand? In the book, we learn that the Elder Wand is passed from one wizard to the other by murder or by being beaten. It also says that the wand would not give itself up so easily... how on earth then did the elder wand give itself to Harry when he so easily stole Draco's wand from him? He didn't fight Draco in a one on one wand duel like how Dumbledore and Grindelwald fought each other.
Even if the elder wand did give itself up so easily, it is implausible because Draco wasn't holding the Elder wand in his hand when Harry stole it: we all know that the Elder Wand was in Dumbledores tomb where instead of getting snapped, it remained intact. Does the Elder wand have a magic interaction with the non-elder wand it's master is holding? Because if it does, it is never explained in the novel.
I think it would have been better if when Snape killed Dumbledore, he would have automatically become the Master of the elder wand, instead of Draco becoming it's master because of Snape and Dumbledore's agreement to save him. Not only that but Harry would not have become the master of the wand, the message that it is not your powers that matter but what you are matter, and another deux ex machina would have been avoided. The third choice here is meant for Voldemorts last stand, when he dies not because Harry killed him or because somebody else killed him but because, since the elder wand refused to kills it's own master, the curse Voldemort was going to put on Harry backfired on himself. It was so anti-climactic.
What if Voldemort really did become the master of the elder wand? He would have become a bigger threat and been more scary. And not only that, what if when Harry faced Voldemort, the latter forced him to engage in another duel with him so as to see who was the better of the two? While Voldemort drew his sword, Harry could have spotten an unprotected nagini by his side and cast the Avada Kedavra curse on it so as to kill it, destroying another Horcrux, before getting 'killed by Voldemorts curse'.
Oh, and I read the last post. We suspend our disbelief and totally believe that an author should twist and turn his plot even if it includes having it's characters going into extremely dangerous or even silly situations, but these events must be coherent. It is rather exciting and scary to read about aliens invading earth but some movies just get spiled because of plot holes. For example, the film Signs has aliens attacking earth... thats scary and we suspend our disbelief because in this world, it could be possible for aliens to attack us. Everything gets ruined though, when these aliens who have technology maybe billions of years more advanced than ours, can't figure out how to open a door or even blast it open...:shrug: Not only that, we also find out that they are... allergic to water. So these aliens are dumb enough to actually visit a planet that is mostly covered in water. Don't tell me that they couldn't have known, because with their technology, I deem it impossible for them to not know that they are allergic to water.
