So Okay It's Average, but Nonetheless Enjoyable
I'm going to make this short. I've only read the first two books, and maybe, someday, if I have time, I'll read the rest. When I first read the first book, the only fantasy I had read before was The Lord of the Rings, and I can assure you that helped my enjoyment immensely. These books are hugely derivative. Moreover, the writing and characterization are very characteristic of young and inexperienced writers, especially fanfic writers, but that didn't bother me at the time; I'm still more forgiving of bad writing than most, if the story can light my imagination, and Eragon did. In the end, it is very easy to get into and more or less enjoyable. It is good, I think, for people who are just starting to read for pleasure and who have an interest in the fantasy genre, since it is very accessible. But more developed readers/writers may have a hard time getting over the purple prose, while fans of the genre will have trouble getting past all the cliches; nobody will mistake it for a true masterpiece like the Lord of the Rings or Harry Potter regardless, but it is worth checking out if you like fantasy and need to kill some time.
