What always irked me about the "fetishtastic" parts of Marv Wolfman's Titans stories was that Wolfman never actually did anything with it. The devolution tank was a prime example: the devolution wore off before the cavemen-Titans even got to do anything.
Likewise, Wolfman's Titans had a tendency to get mind-controlled (or similar) into becoming evil for a few pages, only long enough for a fight scene or a bit of shock value, and then just revert back to their good selves as if nothing had happened. (The Terror of Trigon story is one of the most spectacular examples: Page after page is spent on corrupting and turning each individual Titan evil... and then, after all that fuss, they only stay evil for the total of five pages and do nothing with their newfound evilness other than beat up on Raven and saying "Ha ha ha ha" before reverting to their good selves again the moment the plot no longer requires them to be evil.)
That's one of my major problems with Wolfman's stories, especially when he tries to do something big and grand: The climax is hardly ever worth the setup. I usually end up just thinking "was that was all the fuss was about?"
That said, I'll take the Wolfman's "wait, was that it?" Titans over the current "drop like flies in the most gruesome ways" Titans any day. ^_^
