I've seen a few threads asking who people think are the best artists who have worked on Spider-Man, but I haven't seen any asking who people think are the worst artists who have worked on the character, so I thought that I'd start one and dump on a few that I hate and see what people's general opinions are and why.

My personal pick: Azaceta.

My god, all his work was just terrible and I don't know who coloured his stuff, but they were one of the worst colorists I've ever seen as well (he might have done that as well). He was one of those immense failures that almost never got to do their own covers, lest customers see what their buying and get scared off.

An Example:

That was one that marvel felt was worth showcasing as some of the artists work, so you can just imagine how bad it was when it dipped, god forbid if he rushed.
