I heard from other users that this series are really bad.......

Apart from some points(the White Rabbit etc),I think it's ok.

What do you think?

I just started to read it around the Scarecrow story arc. I think it's been an OK book.

But why people hate it so much?

Don't know where all this hate is coming from either.

I read it since the Scarecrow arc it's not bad it's just so boring that like a day later I can't even remember what happened.

This.

Because they think there are too many Batman books and as this book is average at best there should be another book about a character who is not related to Batman but the truth is there are worse books then TDK but because TDK is selling more than those worse books (probably because many people like it) everyone thinks this is the one they need to cancel.

Agreed.

yeah knight terrors wasn't so good....pretty average..

i like it for only one or two reasons hint hint

@stronger: I would agree that the first tpb (Knight Terrors) isn't the best Batman book out there, but far from the worst. I found its stories less disapointing than the appraised Batman: Death of the Family. Then the 2nd tpb (Cycle of violance) is very dark. Its's a good read and you learn a lot about scarecrow. The 3rd (Mad) is also very dark. Maybe a little less good than Cycle of Violance. You learn a lot about the Mad hatter in this book. Some won't like it because it revolves a lot around Lewis Carroll. I haven't read the other books yet. If you like dark stories do pick them up.
