I'm rather surprised I haven't started posting here yet.
I'm saddened by the lack of Image Comics love in the last few pages I've read. I've recently started reading Image's stuff this summer, starting with a massive compilation of Invincible comics.
Invincible is probably the best super hero comic I've ever read. The drama can get fucking intense, and the plotline throws loads of curve balls you don't see coming. Perhaps most importantly, the status quo is ALWAYS in flux. The series very rarely ever follows a "monster of the month" formula and instead is constantly developing the plot.
Since this I've started reading Astonishing Wolf-Man, Savage Dragon, Witch Doctor, Chew, really just any Image comic that looks creative or is written by Robert Kirkman.
On the DC52 front, I've been following Action Comics, Justice League International, and Blue Beetle. I loved the last Blue Beetle and Booster Gold series, and so far these titles at least haven't offended me yet. Though it is a little depressing knowing the old series won't be continued anymore, especially Blue Beetle. After three issues the new series hasn't quite lived up to its predecessor, but the last series took a little while to really get going so I won't render judgment yet. I'm enjoying JLI a lot more, probably my favorite DC52 series at the moment, though I haven't read the core JL book yet. Action Comics has been....okay. Its beginning to get more interesting now, I'm beginning to like Superman a bit more.
Also been reading Atomic Robo. I'll let one of the FCBD issues speak for me:
