4) Blackest Night
I almost hesitated to count this but then McBride told me to, so here we are. Once a collection reaches a certain page length (and considering I hadn't read any of the individual issues previously), I guess it counts. Blackest Night is the supposed culmination of a years long story where the Green Lanterns started to produce more lanterns of various colors. Each color of lantern (It feels wrong to say "colored lanterns" because it's already bad enough that the ultimate bad guys are the Black Lanterns and the ultimate good guys are that defeat the evil Black Lanterns are the, you guessed it, White Lanterns, but I'm getting ahead of myself.) represents a different part of the emotional spectrum. While green still stands for will, red covers rage and blue is all about hope. Each one, with the exception of the Sinestro Corps' yellow power source, is less interesting and less powerful than the Green Lanterns until the Black Lanterns roll up because they are dead zombie jerks.
