A Darker Shade of Green continues Dave Gibbons' take on the Green Lantern Corps, as things begin to heat up in this TPB. It is revealed that the ever knowing, seemingly omnipotent Guardians are in knowledge of a super-secret faction of Lanterns, which sets up the superb epic The Sinestro Corps War, and eventually, Blackest Night. Prophecies are spewed, promises are made, and seeds are planted for some future, catastrophic events that may very well alter the Green Lantern Corps for the forseeable future. Problem is, A Darker Shade of Green doesn't really do much other than be a lead-in of sorts for the coming events. Still though, legendary Watchmen artist Dave Gibbons provides a solid and often compelling story that will hold your interest regardless. Other than some more sub-par art from Patrick Gleason, A Darker Shade of Green is a worthwhile read for Green Lantern fans, and serves as an interesting prelude to The Sinestro Corps War.
