New Spartan Ops Episodes

Has anyone else checked out the new SpartOps episodes yet? I just played through episode 6 and 7 last night, and I have to say that 343 has really delivered this time. The first set of 5 episodes got repetitive really quickly, in that you were always fighting on the same maps over and over. Episode 6 alone introduces 4 completely new campaign maps, along with visiting an existing multiplayer map. The cave map in the 5th mission was especially awesome! Episode 7 introduced environments in Infinity itself, which was pretty cool. I still feel that the tie between your player and the CG story is really loose, and often very hard to follow, which is too bad. Ultimately though, the missions are fun to play through, and the opening to the first mission of episode 6 was pretty damn awesome. So yeah, thoughts?
