there are many similarities but come on, weve already had the discusion on how hard it is to come up with originality. Oh and heres why i didnt like Eldest nearly as much as Eragon:
1. Eragon became a wuss in Eldest, he spent the entire final battle of Eldest contemplating how wrong it is for him to take another persons life. That is wrong in murder, but on the battlefield there is nothing morally wrong with killing someone. in fact it is required. It doesnt become morally wrong until you start enjoying killing others on the battlefield (well that statement is arguable). He did nothing but whine about killing these guys in what i actually thought was a pretty crap battle.
2. the magic principles that were set up in Eldest were so gay it was retarded. I mean come on, the death words?! What was Paolini thinking when he did that?! What is cool is in Eragon when he killed all those Urguals with Brisinger. but all Eldest was was a battle between magic users. The soldiers did nothing, they just tried to kill the other magic users while their sides sorcerers protected their minds. whenever a sorcerer failed all the soldiers he was protecting instantly died from Eragon's retarded "death words". What i would have liked to have seen was Eragon show up riding Saphira and just go slashing through everyone as she scorched the battlefield with fire and he hacked at enemies from her back and cast fireballs at the enemies.
3. Eragon was not an inteligent fighter in Eldest at all. Based upon the magic system that Paolini made there was no reason why Eragon should have ever become tierd. See, what he did was kill the enemies with "death words" whenever they lost their protection from the sorcerers. What he should have done was absorb the life from the enemies thus replenishing his own energy and strength. then he could have kept on fighting without ever growing weary.
4. About 400 pages of Eldest was nothing but his training. It was basicly just Paolini saying "hey look at me, i have a great vocabulary and am a great writer, read all the crap i want to throw into my book to make it seem epic" (I know that sounds cynical and all, which it is a little i suppose, but come on,k its true!). That book could have been 200 pages shorter had Paolini removed the crap that had no bareing whatsoever on anything. It could have been 300 pages shorter had he removed all the crap that had no bareing on the plot!
Now i did like Eldest, but had it been the first book and not Eragon i dont think id be finishing the series. By now i just want to see Galbatorix show up with a massive army and his new ally (i dont want to say who for those of you that are reading the book but havent finished it) and just rock Eragon, the elves, and the Varden into oblivion.
