It's not exactly TOS, but I just saw the Conan Movie #8 after 2 years of having it on my plan-to-watch list. I didn't feel much nostalgia since everything felt fresh just like way back: the mystery, the action, and my neverending rage at Ran's and Shinichi's romance. I think if DC ever ends, I'll pick up the manga at the last couple of chapters just to see how it's going to be between them.
Just thought I'd share. :T
