Microsoft has released a new, short, live action series, Halo: Nightfall. Written by Prison Break creator Paul Scheuring and produced by Ridley Scott's Scott Free productions, I watched all 5 episodes in one afternoon.
Microsoft's earlier live Halo series, Forward Unto Dawn, was excellent. Halo: Nightfall is good enough. The effects, early SciFi channel-style acting, and just enough Halo lore to get me engaged. I loved seeing battle rifles, MJOLNIR styled armor, Condors, ONI and all the other UNSC goodies. Sadly, after episode two the story was nonexistent, you've seen this junk plot many times.
If you are addicted to Halo, check out Halo: Nightfall.
