While Tuvok wasn't focused on enough, Tim Russ played the hell out of the character. I really enjoyed eps. like "Riddles" & "Meld" when Russ was allowed to break from character. You got to see what great range he had as well as recognizing the disappline he used to play Tuvok. I think one of the most endearing charactistics of Tuvok was his dry wit. I also liked that Tuvok was your typical snobbish Vulcan that looked down upon humans. He actually liked us.
Exactly my opinion too. I always loved that "dry wit" which did show up from time to time. I remember his comment to Neelix, I think it was in the beginning of "Tuvix": "Mr Neelix, do you think you could behave a little less like yourself".
I also agree about the way Tuvok did look at humans. I think he found them a bit primitive when it came to emotions and giving after for them but also very likeable in some way. I also think that he reeally respected both Janeway and Chakotay.
As for Tim Russ, he's brilliant. In my opinion one of Star Trek's best actors.
