So I bought and watched it on Tuesday. Must Say it was really cool.

Origins I & II : Very cool and informative.
The Duel: Awesome story about how the title of Arbiter became a badge of shame and yet powerful at the same time.
Homecoming: Interesting little insight into the spartan program.
Be Human: I WANT THE SUIT!
Odd One Out: About Spartan 1337. FUNNY AS HELL!
The Babysitter: Little insight into why the Spartans and ODST's didn't really like each other.
The Package: Very Cool story about the Master Chief and The Arbiter's first meeting.

All in all I give it a 9 of 10
