It's not as boring as The Moor, but it was WAY worse in that it was a total disservice to the characters involved.

The stuff told from Holmes' point of view was really interesting intellectually, just to see how his mind is working at any particular time, but the writing during those sections is so uninspiring. And whenever Hammet shows up she vascillates between styles and POV like WOAH, and she doesn't even seem to notice that she's doing it. *sadness*
