I will say this.
Would we have seen Marvel Zombies if not for the success of Robert Kirkman's Walking Dead? I think not hell Kirkman even wrote the first story in 2005.
Now I honestly believe from the way it has been set up and establish Blackest Night would have came either with or without Walking Dead.
As for Marvel I have been reading Marvel since X-men were blue and gold team's the 90's but these stories these day are horrible. Just my opinion.
I'm saying my feelings reflect many who have heard of this storyline and Chris Yost and his partner had to defend their storyline.
Blackest Night has been the most hype comic for the past two years and I don't doubt for a second Marvel didn't say well we can do that too.
Though that is part of the business would DC had replace batman if they had not seen the success Captain America had with Bucky taking the mantel?
I see your point but it's getting hard for me to keep caring bout Marvel storylines. though one reader won't break them
