Spidey has had pretty serious stories going back into the '60s. The showdown in Amazing Spidey 121 with Green Goblin is hard to beat, then you had his running into the Punisher in the '70s, and the most effectively dark Spidey story we'll probably ever get--Kraven's Last Hunt--in the '80s. I collected Spidey comics in the '90s, but he fell victim to the same phenomenon that affected everything else back then, and ushered in the "dark and gritty" world of Image comics. Particularly McFarlane's take on Spidey, where he seemed to get more and more creative control. Dark for the sake of being dark never works. I just hated the style, the character designs, and the general approach to comics in that early-mid '90s period. Also, the SNES Carnage game was terrible. I do like my Carnage Minimate, though.
Honestly, I think Sony would be lucky to get Casper Van Dien to sign on until they can prove themselves. Look at what they did for Jaimie Foxx's career.
