Tuvix: The crew of Voyager prove in this episode that they are all amoral cowards. I can't believe that every single one of them would stand by as Tuvix is taken to his execution.
As for my evaluation of the episode, I don't believe that Tuvix became truly interesting until the moral dilemma was introduced two thirds of the way through. With all of that in mind, I believe that Tuvix is an above average episode with a terrific finale.
