Overall I enjoyed this book. It was a fun read, and has humor throughout that is funny without being over the top or feeling forced. Even though I did enjoy this book, there are some things about it I didn’t enjoy very much which made me rate this as a 3 instead of a higher rating. 

This was published ~40 years ago and in some ways it does feel dated. The biggest issue I had while reading is that there were a lot more references to (and/or threats of) rape than I was expecting. To me it feels like this is included so frequently because rape is what Bad Guys do, which is not something I enjoy reading. Also, because the writing style is on the more lighthearted and humorous side, serious topics (ex. Rape, murder, war, etc) were handled in a way that felt casual, dismissive, or humorous at times, which felt weird. I think most of this is just that it was written in a different time so I am not holding these flaws against it too harshly - but it is something to note if this will be a problem for you.

That being said, if you can look past these complaints, I did find it enjoyable. It was not especially deep, and was not very focused on the sci-fi elements, but it was fun. The main characters felt somewhat flat but were likable.
