If you're really in to superheroes you should check out Invincible. It starts out like a typical teen hero comic, but by the second volume it takes a completely new approach to the genre. You should also look for the Mini-series Meltdown. There are only 2 volumes and its premise is as followed:
MELTDOWN tells the story of a reluctant super-hero whose own fire- based powers are killing him; melting him down from within. He's only got 7 days left to put his life in order, and to make amends for all of his regrets.
Both of these series have great stories/writing and a great deal of well thought out action.
