It's hard to criticize Geoff Johns, for he made Green Lantern and Hal Jordan a top selling comic book. I don't think Green Lantern had ever been consistently in the top 5 to 10 sales wise before.
That being said.....if I had to pick a bone with Geoff Johns, it is that weird authoritarian right wing tinge that popped up in Hal Jordan from time to time, that I do not recall encountering before (Denny O Neil to my recollection, just painted him as a straight man in comparison to Ollie's left wing rhetoric)
I remember in particular, being really pi$$ed off by this....(bottom panel in response to Ollie's comments about cameras)
