I thought, that I will like it more, than I actually did. So in a way I was disappointed.
Firstly, I made a mistake by watching a movie first. And I have to say I liked it more, than a book. The writing style was enjoyable, however there were too much scienetific terms for my taste. And for that reason it was hard to get into it for the first half of a book. After that, I got used to all those terms and was hooked.
The best part was the main character and his sense of humor in critical situations, there were some parts, that made me giggle. Also his optimism was contagious and made me think about some things in my life differently.
So I recommend this book for those who like science fiction. I think you definitely enjoy it.
