One really cool short story can't make up for a pair of truly terrible features - a disjointed pair of hackneyed comic tropes (superheroes vs. time travel! and superheroes vs. magic!) that belong in the chemically hazed Disco era, not a modern comic shop.

An interesting parallel world story and a wonderful one-shot make up the first half of the collection which is completely ruined by an incomprehensible Bizarro story.

A collection of odds and ends - one shots and annuals skipped over in the preceding volumes.

If the new 52 was supposed to be all about continuity what the shit is this? New artists are fine, new styles are fine, new storylines are fine. Changing all three at once - as has happened with the last two volumes - and you're not really reading the same comic anymore.

A) If it isn't Bruce Wayne, it's not Batman. 
B) Interrupting the story to preach about the people in the inner city for an entire issue is not entertaining.

The Batman and Joker stuff was good, but that was a single chapter in a 10-issue arc, not enough to forgive poor art, an uninteresting villain, underdeveloped alternate universes(??), and to many deus-ex-machina plot miracles.

A piece-meal story, poorly told.

Why? Frenetic and spastic storyline-jumping? A giant bat-dragon sidekick? Far to many heretofore unheard of locations? Excessive use of red print on a black background? These and more sins overwhelm the book and made it a chore to read.

Cease publication quickly ,and be forgotten.

Interesting idea with a strong start but a very weak middle and ending.

There are plenty of worse ways to spend 20 minutes. Do one of those worse things instead.

A doorstopper at almost 500 pages, but it never feels padded or logy. All the elements are there that you expect, entertaining as ever.

One trick pony , thankfully cancelled.

Hardbound collection of stories Scalzi sold individually already, all reinforcing his lefty-fascist tendencies.

Decent world-building, waiting for more volumes to judge.

Spastic and inconsistent artwork, fragmented and incomplete story arcs, and a bonkers conclusion that stretches the bounds of even comic-credulity beyond the breaking point.

Even taking in to account his rogues gallery of freaks, Batman and his associates are wayyyy to accepting of the premise of pan-dimensional anthropomorphic reptiles in battle with a clan of ninjas.
