Yes it is. The first thing to note is that he had a long run spanning many, many years, and usually his books reference one another heavily. So if you didn't read the books before you may not understand some things and some of the stories are more obscure than others. There are also a bunch of crossovers with the other characters and the Justice League that he heavily references and that affect his version of Batman greatly. Not to mention retcons and the fact that his run continued from the Post Crisis era into the New 52.

Batman RIP in particular stood out to me. He uses a lot of complex metaphors, pulls characters and alter egos from nowhere, uses mystery, red herrings, leaves loose ends, employs flashbacks out of nowhere, and I still have no idea what happened in that book. He just has a very complex way of writing and explaining things. He is a smart writer and his work is great, but this is not what you want if you want simple. Read something like Year One or Hush.

@jayc1324: Absolutely loved Hush, read it twice, thought Year One was ok.

Morrison is a writer who isn't very well suited for the comicbook medium of monthly ongoing adventures, because when his tales are broken up and take the twists and turns they always do, then yes, he is confusing. But if you get all of the needed material and sit down and read it all in one go, then it becomes something else.

Prime example of this is Final Crisis, when that came out, people got irritated and upset that it didn't run like they were used to (ala Infinite Crisis that was mostly about preposterously big action). But then the whole thing was released in a collected edition, and hopefully you get one that also has Superman 3D, and you get a much better sense of what is actually going on. But it's still not simple writing because Morrison is a man who loves to inject metaphors into his writing, some more obvious than others, like Superman=sungod is a favorite of his, and it's not always clear why he does it and sometimes it's just confusing.

His Batman writing though, when it comes to Bruce, then yes... because Morrison has a certain fondness for the long-format kind of stories where he fights one Bane-like hulk in a batcowl in one issue and it's not entirely clear why before a few issues later. Also he tends to want to break Bruce down to the ground before having him rise from the ashes. I don't think he's quite as bad when the cowl was handed over to Dick with Damian as Robin, that was more playing around with reversing the usual Batman and Robin dynamic.

Of course, it's Grant Morrison.

I can see why people might think that but personally I never had that problem. The only time I can think of right now was Batman Inc. I had no idea what was going on most of the time in that book.
