There was a lot that worked with this comic, including the previous three issues leading to this conclusion. The art, the characters, the dialogue... but it all started to fizzle between this issue and the previous. The previous ended on an ominous note, leaving you with confirmation of something that you sort of expected to happen. The final issue really played out all too quickly with a handful of stumbling blocks for the protagonists, which you would expect to be resolved in the long run, but rather, they were wrapped up rather quickly.
I will stress that as a run, I enjoyed this series. I think the creative team did a great job, but it finished a little flat. I would recommend this to people, primarily if they read it all at once. The wide cast of characters spends most time focusing on only a few, and the others are less memorable if you've read each issue weeks apart.
A day after I read it, I'm still not certain that I would have enjoyed it better with 1 or 2 more issues or what changes if any would have made me enjoy it more, but as it stands, the last couple of issues felt rushed, and I guess I just wanted to spend a little more time with the characters.
