I had high expectations when starting this book, and I was not disappointed. Not one bit. 
 What really makes it good is the style, especially Mark's voice. It manages to make what could be really dull (very technical bits, and things happening very slowly) seem so interesting... and absolutely hilarious. I wouldn't have minded keeping to this point of view, but the way the whole thing was handled made it all ok. 
 When I closed the book, I wanted more. I completely get why it had to end where it did, but I wanted more. 
 Not sure what the movie will be like, it could be great but there's a chance that they'lll completely butcher it, since, once again, what really made it for me was the writing. I guess we'll see... 
 (there were a few things that I didn't like, but overall I loved this novel, and I'll definitely read more by Andy Weir !)
