Watched Sarek for the first time in awhile, and it's a very solid episode. I remember as a teen being somewhat bored with the lack of action, but now I find the tremendous acting from Stewart and Leonard is MORE than enough to carry the story.
Although I have to say, in HD you really
notice just how painted on Sarek's makeup is, and it can be awfully distracting at times. In fact you notice that kind of thing with a lot of the makeup now, especially with the aliens (I shudder to think how painted up Quark will look in HD when we get to that point).
