I love TOS and ENT but they only have 2 great seasons. TNG has more, and those shows never made me cry like The Inner Light
did. As I grow older, I appreciate TNG's serious approach more and more. While DS9 is my favourite Trek series, I think Picard is the Trek captain that most sums up Trek's ideals.
Whenever I find myself in a stressful situation, I try to apply the calm, rational, intellectual approach Picard would take.
