Batman: Hush boasts a ridiculous amount of characters from both the hero bunch and rogue's gallery. Pairing Loeb's noir style with gold-standard Jim Lee art, the love child of talents is a comic book buffet of over-the-top action with a healthy serving of mystery. 
 Now just like in the buffet restaurant, every grub demands to be munched because all of them looks so tasty. That's where the problem starts. The reader may be so full that s/he cannot take anymore of the comic food. Batman: Hush is like that. It is tasty to read, but at some point you may lose track of what you are reading because of the sheer amount of things happening in it. The reader is barely given a breather, and what s/he experiences is panel after panel of action and mystery. 
 Not that the Hush storyline doesn't have something good to offer. From Loeb and Lee? No, it has to be good. In fact it is, but there is just too much goodness in it that I wasn't able to absorb everything. By the end of each issue I still have to reread some parts only to understand what really happened or what has developed in the story. I can say that there's two main questions in the book: One, "Who is Hush?" and 2. "Who is behind everything that's happening?". The mystery unfolds like a much denser version of The Long Halloween coming to a full circle at the very end. 
 The action choreography is undoubtedly Jim Lee. And IMHO, his art is at the forefront of this era of comics. I have nothing against the writing and art individually, though when put together, there is this feeling that the mix isn't entirely organic to create the story it should have become. 
 Yet, I liked Batman: Hush. It is a good go-to comics if you do not have something in mind, just something to read in order to kill time. I feel that it was better to read it in individual issues than as a collected edition. The story doesn't stay in your heart like the Killing Joke or even Under the Red Hood, but just enjoyable enough to be a recommended read.
