One of my favorite runs was Roger Stern/John Romita Jr.'s AMAZING SPIDERMAN 224-251 run (from 1982-1984). I don't think any creative team has ever handled the character better.

The Hobgoblin was introduced in issue 238. And there was a very exciting buildup while Stern was scripting the series, that petered out as soon as Stern left the book.

My nominee WTF storyline was where whoever was scripting the book around 1988-1989, (Tom Defalco? David Michelinie? ) revealed (in total contradiction to all the past clues given to the character's identity) that Hobgoblin was Ned Leeds (issue 289 ).

????!!!???

Truly, WHAT THE F---.

I even wrote Marvel at the time with a lengthy list of the clues, and even suggested several ways they could repair the story in a way that made sense and didn't insult readers' intelligence.
