I didn't pick it up. I enjoyed King's Watch, but thought Gordon suffered most from the updating. I do enjoy Parker's work though.
Ultimately, "King's Watch" was a lot like "Masks" only with better artwork and storytelling structure: It's a team-up of the characters in name only as only Mandrake and Lothar are compatible to their comic strip counterparts. The others are all "new" characters. And, once it was apparent that the whole thing was a stealth Flash Gordon prequel reboot, the ending was pre-ordained. I find that with Parker's mini-series, I often enjoy about half of the story but they always fall apart in the last issue and leave me wishing I hadn't bothered. However, I am enjoying his run on Aquaman so far.
The first issue of the FG ongoing was ok, but overall I felt this was a story I didn't really care to revisit. I am familiar enough with his first trip to Mongo, uniting the various factions and overthrowing Ming, that I didn't really care to read yet another version of the same story that I've seen in cartoons on tv, in the movie theater, in comic strips and that Dynamite themselves just re-told a year or two ago. Set up a post-Ming status quo and move on to new stories, new threats and adventures.
