Im not trying to be a hater but I thought Invincible was awful. I read up to issue 15ish and gave up on it. Another to mention of Kirkman's is Thief of Thieves which is not for everyone and is just OK. Dont get me wrong, I LOVE The Walking Dead, one of my favorite titles! But I dont think Kirkman is "that" great of a writer. I would put Lemire, Snyder, Vaughan, Bendis, and Johns in front of Kirkman.
Can't really call a title awful if you only made it to issue 15. The book has over 100 issues. It does take a little while to get sucked into the universe, but once you do it is great. What didn't you like about it? Speaking of Snyder did anybody recommend American Vampire or Severed? Incredible books
