A large portion of my dislike was due to the art. Ezquerra is a talented artist I'm sure, but I just don't like his style.
Bolland did a couple of issues in the first half of the book and his stuff I loved, I've already gone back to reread it. McMahond as well, great clean line work, nicely detailed.
I'm afraid the art is a big factor for me in comics, and as much as I tried, I just couldn't get behind Ezquerra. Because of this, I find it off-putting and the stories are hard for me to enjoy.
After doing some reading, I realize this may be a problem since he is a co-creator of the character and a prolific artist.
Burn him. BUUUUURRRRRN HIM!
ahem.
Actually, whilst I love Ezquerra's earlier art, certainly more than stuff he was turning out in the mid 90s, I can fully understand why some people would find it a little jarring. Its not "clean" art at all, not in the style of Bolland or Smith, and it has more of an organic feel to it.
You may find that his later work, when coloured, is far more to your tastes. Others have suggested The Pit as its the perfect story with the more proceedural aspects you're looking for. This does have a lot of Ezquerra's art, but its coloured and his style has developed a lot since the days of the Apocalypse War, so maybe you could give that a try.
