I enjoyed both books, but I have to agree with the "too much" part of the battle descriptions. Thing is, I don't know how you don't write what Jim wrote. How does he not include something about each of the characters? He has so many characters involved, and he kind of HAD to write something about each of them. So, never ending battle.
The Battle of the Bean came off as a bit ridiculous, with too many characters to take a look at, and none of them getting enough focus. This is a limitation of the first person POV writing style. I don't know if it's possible to write about a battle involving so many amazing characters from a first person POV. By it's very nature, it ends up being disjointed and "vignetty".
I think Jim was in a trap of his own making. Too many beloved characters that he HAD to write something about, and not enough about any of them.
I wish we had seen more of the Archive. As far as I can tell, Harry never even talked to her.
Drakul and the Black Court were a distraction, but I suppose it is setting up stuff for the future. That is really the only explanation. Those pages would have been far better served focusing on further developing other characters or Harry's relationship with them.
Overall, I enjoyed it, but I really do think that this series cannot support this many characters in one book. I look forward to Mirror Mirror where the number of characters involved is necessarily cut way back.
