@Darrell Yeah, agreed. I liked the change of scenery. What made the run great for me was that John was getting pretty depressing before it and Azz made him kick ass again.
@Holmes: The first trade is out of print but it's up on comixology^^ You should read the last few issues of Ellis' run if you haven't to. The last issue of his gave him a jail sentence if my memory serves right.
Like Darrell said, you should read the run in one go. And if you're an Azz fan already, though the ending issue was just okay, then again some other runs also had weak endings.
