That Spock has faced Half-Breed Discrimination has been hinted at in the original series, but this movie shows he's been faced with it since he was newly born, with even his own father making a disapproving "so human" comment upon being presented with his newborn son.
While it's not considered one of the best trek movies, McCoy's hidden pain — making the decision to take his dying father off life support — is truly moving.
Kirk sitting round the campfire with his friends telling them that he expects to die alone.
Syboks's Heroic Sacrifice was a bit of a tear jerker. His Badass challenge to the God wannabe was a good way to go about it though.
Sybok: I couldn't help but notice your pain!
God: (scoffs at the idea) My pain?
Sybok: It runs deep, SHARE IT WITH ME!
Only a member of Spock's family could make that sound badass and still be a tear jerker moment.
The true tear jerker is Sybok's utter heartbreak upon learning that the God he sought was an impostor - and his realization of It's All My Fault.
