I found the first episode to be the best so far (despite that Elite casually strolling through a shopping center) I want to find out about what the element really is and how it was created, but I doubt we will learn much about it with two episodes left. It's obvious Locke and someone else is going to survive, and it doesn't help that besides him, Aiken and Macer, everyone else is expendable. It was nice to learn the motivations behind the humans mining it, but still I want to learn more about the element. Unless they are saving it for Halo 5 or other media in the future.
