I have heard about comparisons being made between Eragon and Harry Potter or Eragon and Lord of the Rings, but I would like to not go into those. I was primarily attracted to Eragon since I was reading a lot about this in media. The book is responsible for making dragons most loved mythical animals. To me it was a love story between Saphira and Eragon. A love that was based on strength and care about each other.
The most important aspect that I liked was the concept of creation and storage of energy which is then used to create magic. The idea almost look plausible at times. It is as though Paolini has figured out some advanced form of energy creation and storage and then he is just converting that energy for either material transformation, communication or transportation.
Saphira is not a slave to her master. She is a friend to Eragon, she is also a master and servant at the same time. She loves Eragon but can get angry as well. They both learn from each other and both get hurt together. Even though there is another love angle of Eragon with Arya, I did not find it as interesting. Arya by definition is too mature for him.
Sometimes, I have felt that he made the story too long and brought in too many characters and then found it difficult to manage them. After sometime I got lost. I have read the other books as well and there were some interesting concepts there but I will write about them later.
