I'm not the biggest fan of DC. I like people (Martian Manhunter, Johnny Sorrow, Kyle Rayner, etc.) but the story arcs never appealed to me much.  But Darkest Night is surprisingly focused on the dual storylines, and the story has not stagnated to any extent. The new Lanterns are drawn well and interesting characters to boot.
 
I don't like Dark Reign. Dark Avengers has been disappointing for so many reasons. It's frustrating to see the Dark Avengers, individuals with power sets that could potentially challenge the previous Avengers teams, constantly fail to complete objectives over and over again, especially since they're not stupid in any sense of the term. Norman has not done shit since he's come to power, and there's no fun in watching a very incompetent villain wield great power. The realism bites them in the ass when the reader realizes how much of the storylines and characterization are meaningless or non-essential. I did enjoy Dark Avengers: Annual #1 and the current issues of Thor (big sucker for Marvel Boy and Thor).
