So Lasky picked up the beacon or whatever it was that Cortana said she'd drop at the end of Halo 3, and then has a flashback when he goes through the transmission. Hmm.
From a critical standpoint, the first episode seems like a cheesy, average, coming of age story with a new skin on it.
But as a Halo fan, this is great to watch. Personally, I'd take this over a feature-length movie tie in. Forward unto Dawn (as well as The Thursday War) is PERFECT for staving off my hunger to play Halo 4.
