I think the Chattaway disc is the biggest disappointment for me. Almost everything before "Call to Arms" isn't especially interesting (although the "By Inferno's Light" cues have their moments). They should have included more of his emotional cues to balance out the action.
The McCarthy disc is very surprising, in that I find the earlier material to be more interesting than the later, at least as presented here. Who knew that the score from "The Storyteller" was so interesting? Of course, it's virtually dialed out in the episode.
