The "alien-comes-to-earth-the-first-time"-concept is nothing new (in fact, I had to think of Marvel's first Thor movie a lot while reading this), but Matt Haig manages to put an interesting spin on it. It's funny and philosophical in a way that will stick with me for a long time. It DOES have its lenghts though and the last few pages contained some of the cringiest sentences I've ever read. I also think that it focused on the protagonist a bit toooo much and neglected the development of some side characters.
