I have many reservations about Star Trek, such as its crude treatment of socialism (see also here). Still, the original Trek and several of the TV series that followed (especially my personal favorite, Deep Space 9), used science fiction to address important issues in an interesting way that could appeal to mainstream audiences as well as genre fans. The Spock character, as played by Nimoy, was often at the center of that.
I'm one of those "genre fans," and a bit of an elitist. I refuse to watch anything beyond TOS (the original series).
In the comments I learned this:
Kirk taking over Canada while Spock retires.
