I want to preface my comments with this: I still really like this show and I like Tom Sellek.
Having said that, there's this little nagging thought in the back of my head. What if Tom Sellek had the ability to act? Though Tom is an essential part of every episode, he is generally not at the center of the story and all he has to do is look concerned or annoyed, or upset (which are all the same expression as far as I can tell) and speak his line when prompted. But the limitations of his acting ability really impact stories like the one told last Friday. Tom's character went through a range of emotions all of which were interpreted by Tom as essentially the same expression and the same delivery. It really impacted the way I thought of the episode as "not so good". It triggered my imagination of how differently this character would be if portrayed by someone with a range of acting ability rather than a former male model who could speak lines on cue with reasonable emotion.
Just an observation.
