I can cite one word that will anger every GL fan: reservoir. Maybe two? Carol. Maybe three? Soranik.
Venditti's Hal Jordan & the GLC has no soul, no logic. The theme of the last story arc about no-killing is absurd. The four main Earth GL are all stereotyped to fit in his stories. He tried to surpass Johns in New52 and he failed. Then he tried to imitate Johns in HJGLC. The art is good and there are a lot of fighting scenes. There are good moments. But overall it is still an unsatisfying run.
BTW, Cullen Bunn's Sinestro is great.
