Original Star Trek reflected the Cold War era it was made in -- high ideals and a wish for peace but grounded in the "Teddy Roosevelt Great White Fleet" kind of militarism. The evolution to the TNG period makes sense but yeah, I'm excited about the reboot cast being together again (says the guy who was a fan of TOS the first time it aired in the late 1960s).
edit: Heh!!! Bawwwwwwwww!!! Bawwwwwww!!! The noise just won't die
