I read the latest Ex Machina TPB (volume9, "Ring out the Old") and I have to admit, I was actually a little disappointed. But be warned, this post will contain spoilers
I have enjoyed this series and one thing I've actually liked about it was avoiding making the story about his superpowers and instead focusing on his role in politics and the people around him with the powers remaining in the background. So I enjoyed the first bit of this TPB that dealt with finding a comic team to tell his story in comic form or the environmentalist story but once it got into talk about magic cubes and preparing Earth for invasion I started to lose interest. I suppose they have to eventually reveal the secrets of his powers but it felt like the story was getting away from what I liked about it. I hope I'm wrong and the next volume changes my mind but we'll have to wait and see.
And please, if you're reading this monthly please avoid posting any spoilers in the comments.
