Not only have writers always had trouble writing Jameson, his bad characterisation may also be a result of Marvel never stepping out of "let's make Peter's life miserable... again" and Jameson being Peter's boss and executive of a major news paper that covers Spider-Man opens up so many ways to give Pete a hard time.

Peter's life sucking and Jameson being douchy always bothers me about Spider-Man stories. Then Superior came along and they managed to make Jameson a bigger douche. O, how I hated the character's guts.

EDIT: Thank you for clarifying Jameson's character a bit. Now I can have some sympathy for his strings are being pulled by those who sit in the shadows... or offices.
