i won't say that i was convinced by every argument chugg posits here-- some of his conclusions seem like he took a big leap to get there, and he had a tendency to make things sound like he was stating facts when further reading would reveal them to be opinion or interpretation.
now, to be completely fair, i don't read much historical academia, and i come to research from a science background, where hypotheses have to either be tested or supported by enough evidence to hold weight, or the dreaded "more research is needed" must be included along with any conclusions drawn. i'm aware things are very different when it comes to historical research, but it may be that i'm just not used to how different it is. so i'm not going to knock chugg for a style that might just be part and parcel of the discipline he's writing in.
in reality, as you can probably tell from my rating, i learned a lot from this book, and it introduced different perspectives on aspects of alexander's life that i DID know, so i really appreciate it. and quite frankly, it's nice to have most of our collective knowledge about hephaestion compiled and presented in an easy-to-follow manner, and for him to get some recognition for his accomplishments. dude has been so maligned throughout so much of history probably because of homophobia.
