The amount of imagination and creativity on display in this current run has been impressive, to say the least. Grant's work, adding to the mythos while shaping his arc has been entertaining thus far and I am very interested in seeing where this wild ride goes next.
This might not be a must-read by standalone standards, but as another brick in the foundation of the overall series it's well worth picking up.
If you are a Hal Jordan fan, please consider reading this run. I think you'll be pleasantly surprised.
