Justice League Dark is a fun read. The addition of new characters and greater emphasis on action have been positive changes. Although, I was one of those (few?) who also enjoyed the earlier issues with slower pacing and more focus on character relationships. The artwork was also more solid, back then. But I have few complaints. Honestly, I'd buy this monthly just for the awesome cover art. I recommend it and keep coming back monthly.
Stormwatch is the DC book I'm most excited to read each month. Every issue does something I didn't expect, and unfolds new aspects of the characters and their relationships. There's never a dull moment, and page space is used to good effect. I didn't think I'd like this series, and I was very skeptical of the chosen characters...but I love it. I didn't want to see ____ leave the team, but it hasn't hurt the book one bit. I can't get enough, and highly recommend.
Swamp Thing is what I call high value. Art, story, every aspect is top-notch. I dropped from my pull awhile back, because I just wasn't feeling it. With work slowing down, I might pick this one back up along with a few other titles. Although, I still have to read all of Alan Moore's version. The few that I have read were exquisite. I'll probably read up on those before coming back to the current run.
I just read the latest Frankenstein, AOS. I love stuff like this. I haven't touched this title in a really long time. It looks like I've missed out on some cool stuff. Will probably buy up some back issues of this one.
