One of the things I enjoy about Voyager is that Tuvok gives the show a more consistent vulcan presence, which was missing in The Next Generation and Deep Space Nine (where the most memorable episode with vulcans put them at odds with Sisko, albeit in only a mildly antagonistic way). So it seems that Tuvok was the first new major vulcan character since Spock? Anyway, vulcans are one of my favorite Star Trek aliens and Tim Russ did a great job getting the vulcan mannerisms down while imbuing his character with his own distinct personality.
