^ Excellent choice, very emotional scene.
Nothing in TOS made me cry. DS9's The Visitor made me a wreck though.
THE VISITOR would have had me weeping if not for the lamentable age makeups that plague all of ModernTrek. Everybody always has this shine to them like they're plastic, and I find it distracting as hell. I actually often listen to THE VISITOR rather than watching it, at least the parts with Tony Todd playing older.
FAR BEYOND THE STARS often wipes me out too.
