Bond's loyalty to M is tested when her past comes back to haunt her. Whilst MI6 comes under attack, 007 must track down and destroy the threat, no matter how personal the cost.
"2001" is a story of evolution. Sometime in the distant past, someone or something nudged evolution by placing a monolith on Earth (presumably elsewhere throughout the universe as well). Evolution then enabled humankind to reach the moon's surface, where yet another monolith is found, one that signals the monolith placers that humankind has evolved that far. Now a race begins between computers (HAL) and human (Bowman) to reach the monolith placers. The winner will achieve the next step in evolution, whatever that may be.
