To me, the TWO BEST Spider-Writers were MARV WOLFMAN and J.M.DeMATTEIS!
Don't get me wrong. I liked RogerStern's Spidey--but ONLY half of it! I remembered him from SPECTACULAR SPIDER-MAN so when I saw that he had taken over Amazing SM, my heart sank! And for the first few issues (Vulture to Black Cat depowered) my fears were realized. Then he did that wonderful Juggernaut story, only to follow up with a string of mediocre plots: an O.K. Mr.Hyde story then an abominable sequence that seemed to go on forever, as The Tarantula was transformed into--a GIANT TARANTULA! Then here we go with The Vulture again, one of my least favorite Spidey villains. But before all seemed lost Stern just went on a tear where it seemed he could do no wrong.
Sure the Hobgoblin mystery was the first "Who is The Green Goblin" saga, warmed over, but I didn't care--I bought every issue that had him on the cover! So, I think Roger ended his run on a high note but after a VERY slow start!
By contrast, Marv's tenure began with Three just O.K. villains (The Rocket Racer, The Big Wheel and The White Dragon, who's not bad at all, upon reflection) but their weak status as baddies was barely noticeable because the STORIES were so much fun! Spidey's razor sharp "quip" machine was back! Peter Parker had also returned (under Len Wein, Parker was often M.I.A) and Marv's expertise at folding in sub-plots and counter sub-plots (a skill honed on THE TOMB OF DRACULA) was in top form! When Stern's tenure ended, it bothered me but I was willing to give Tom DeFalco a chance. When Wolfman left, I was FURIOUS, ESPECIALLY since I had just re-newed my subscription! The silver linings for this "dark cloud" were Marv's next two projects: BATMAN and a little comic called THE NEW TEEN TITANS! (Oh, and I almost forgot, a brief but exciting tenure on Action Comics!)
As for DeMatteis, well, I've already praised his work numerous times on the Spidey boards so I'll let those suffice...
