Typically I shy away from Thor comics because I tend to be confused by them, but I actually grasped most of what was happening in this graphic novel and did enjoy reading it. 

All the protagonists were easily likable and neither their seriousness nor their comicality ever felt false or forced. Multiple quotes stood out to me as having meaningful application both in the context of the comic and in our reality, and the visuals were beautiful. 

Even though the events in this story may not match up perfectly with Earth-616 canon, they do give one a good understanding of Thor's world and I recommend that other people new to it should read this as well.
