I have very mixed feelings about this book. I loved the concept. I wanted to know, just like most of the people in the book, if Watney was going to survive and get rescued. I also liked the structure of the book with the different modes of narration and settings. Now onto what I didn't like. Most of Watney's logs sounded way more like scientific journals than an actual fiction novel. I know that must be done to fully explain what was happening but I am more of a fan of lighter sic-fi where I don't need to really understand the science behind everything. I have a feeling that I will like the movie, however, since so much can be shown visually and make sense. I also wasn't so much of a fan of the characters. They all seemed so similar to each other and were more like cardboard people filled with stereotypes than characters I wanted to read about. And don't get me started on Watney's sense of humor. It was pretty bad. All in all, I liked the concept and but the actual execution of it I wasn't a fan of.
