This book is less bad than a disappointment. This is the first volume of silver age Batman exploits not tainted by old school cornballs Gardner Fox and John Broome. It should be a progression, but in reality it's a regression, as the staleness of these so-so modern crime tales gets dull.
The art wasn't bad, wasn't great either. Neal Adams is a great artist, with his huge sense of scale, but he's largely disregarded for Irv Novick and Bob Brown. Brown has a solid career, doing things like "Marvel Two-In-One", but with Batman it seems kind of flat, aiming for a blend in realism. That's the same thing I get with Novick. It seems to avoid an association with showy comics, but also avoids adding anything else.
The writing was the biggest let down. Denny O'Neil is one of my favorite writers of all time, but he only writes a few fill-in issues for Frank Robbins, who really has an issue with creating interest with his comics. Batman fights criminals, which seems standard, but the criminals are weighed down with their constant ability to fail, little middling issues of their humanity and how crime really doesn't pay. It gets more intolerable with its constant repetition.
Let's look at the "biggest developments" in the book for examples:
-Robin goes to college: Makes sense based on the age of the character, but the comic really seems to make it seem unimportant. It doesn't get mentioned again, and Batman fighting crime is the same as Robin fighting it, just with less bodies in the panel.
-Batman moves his headquarters from the old Bat Cave to a small basement in the Wayne Foundation building: Again, it kind of makes sense, and the office building makes his day to day adventures less arbitrarily garish. Plus his new "camouflaged" batmobile sportscar looks cool. But these details lose their attention after a debut issue, it still feels stale.
-The introduction of the Man-Bat: It seems like a big character. He's actually a monster, it reflects Batman's pathos, etc. LIES. Man-Bat is a nebbish little bat studier who starts looking like a bat and does crime things. But Batman keeps a constant air of aloofness and superiority around him. Man-Bat is just a generic criminal with a slightly more erratic trajectory and a longer origin story. It makes Batman seem emotionally aloof to everything in the world, at least by this example.
SO, basically, it's not bad, it's just kind of boring and dull. 3/5
