I finally finished season 1 of Spartan Ops this past weekend. Wow was the 10th and last episode ever good! Episodes 1-5 left me a bit dry, but episodes 6-10 overall were a big step up in map and story quality. The story in the last 3 episodes was the quality of a very good video game. The ending was a cliff hanger, but I mean that in a very positive way.
Can't wait for season 2; just hope I don't have to wait too long.
I'm very impressed with Spartan Ops. For anyone who really enjoys Halo, IMO it easily justifies the purchase of a XBLive gold account.
