I am just having a really hard time getting into anything Halo post-2010 as of late. Halo is one of my favorite things ever, but the story pretty much ends with Reach for me. More and more, as I see/hear things about the current direction that the series has been going, my interest wanes. And given the characters and such featured in this, it is going to have to be soaked in all of that.
The time for a big live action Halo project has long since passed, I think. It would have had to come out somewhere between Halo 2 and Halo: Reach for it to really hit with the right kind of impact.
