This movie was indeed epic. I can't wait for the next chapter...
You could see some glitches (mostly reflections and lenses), but it overall got close to a very professional level.
I would put up my three thumbs up if I had them, put posters of it in my chamber if they would be released, etc.
The music was also very high quality, and more importantly very fitting to the atmosphere of the moment.
The most funny part was the part after the ending credits.

Gary: Don't press it, don't press it! I'm telling you!
Dude: Oh my god!
Gary: Nooo!
Dude: Aaaaaaaah!
Gary: Ah crap..."

Quote: "Pierre: Snake... Could you explain one thing to me?
Snake: Yeah?
Pierre: Why are we standing in front of the window, during war time?
Snake: Mhm... Not sure.."
Quote: "Santa Claus: Are you Solid Snake? You're on my naughty list this year! You killed 17 people last month..."
Quote: "Pierre: Hey big chief... Don't you think this is ending an awful lot like the Two Towers?
Snake: Naah. Don't worry Pierre, I mean, it's not like they're gonna end on an upward panning shot... *camera to upward panning shot*
...against ephemeral music... *ephemeral music starting to play*"
That's what I call memorable :-P
