The first problem I had with Jim was when he retconned everything that Thanos previously went through when he left the company years ago in the late 90's just because he didn't like what his character had been through without his input.
Now he has been writing everything on Thanos with his dated art and "Thanos is the smartest most powerful" blah, blah, blah.
After reading Thanos vs Hulk#2 (in the comic shop because I'm not buying his crap), I realized how much he caters to his character. Simply put; Starlin sucks! He needs to stand down and let somebody else take the reigns in writing his character.
And btw, We all know Thanos is a carbon copy of Jack Kirby's character Darkseid, but I hate how Starlin never gives Roy Thomas co-creator status on Thanos because he had a hand in his creation.
