Defenders Namor #1 second print

While I was impressed by Marvel going back to its roots and recreating the Defenders in a way that reflected their original starting point, I quickly grew confused and annoyed. Namor the Invader, the Avenger, the X-men all seem to be gone and he's devolved into the infantile half man that was prone to temper tantrums. And while Chip Zdarsky's story is the perfect telling of that character, it makes me wonder what happened to all those years of Namor. Namor's own rage basically gets him killed until the intervention of the Silver Surfer's Board? This gathering of heroes is all over the board and don't even get me started about the guy in the sheet. I lived through the Elf with a Gun.
