Watched it. GODDAMNN! I got chills. The dialogue was somber, no-nonsense, straight-up storytelling and then the inhumanly confident boast: "I won't" in reference to Cortana's concerns about missing. When he opens
the airlock and Earth is under full scale attack. A frigate evaporates before his eyes and small ship combat zipping all around. Then with the deed done, he lands with a thud onto his ride down to the surface to kick MORE ass. How many lives did the Chief single-handedly save during this engagement alone? NICE!
