The acting in TNG is pretty bad indeed, but I think the character design isn't too bad on any Star Trek shows, although often quite cliché. My judgement might be impaired by nostalgia, but i love all the characters on Voyager in their own way. B'elana and Neelix being my favorites.
It's probably not very difficult to meet my expectations for a Star Trek show as long as it stays true to that old flare and introduces some funny looking aliens. Just hope they don't try to make it into some sort of Michael Bayesque blockbuster in series form.
Any guess on who that actor is?
