It was a very emocional story and well-written retelling of the Iliad. I really liked the way the relationship between Achilles and Patroclus progressed and it didn't feel forced but i would have prefered even more  scenes and dialogues between them. I thought it was a great choice that we read the story from Patroclus's point of view even though Achilles is always the center of every story related to Iliad.  I also like that the story explored some secondary characters.  
 The narration focuses very little on the battles but at the same time doesn't shy away from the brutality of the war and for me that was the right choice. 
 The ending was bittersweet but it fitted the story perfectly.

Their story was meant to be tragic from the beginning anyway.

 
 I liked how the gods were represented but especialy the heroes and the demigods. Even though it was made obvious that they had something "more" than the rest of the mortals, that didn't mean they were perfect or that their divinity was a good thing.

The contrast between achilles and his son neoptolemus was the most obvious example that makes perfect sense once you read it.
