These are the main 2 reasons I gave it a B. I find the IC characters & their stories more compelling overall, and found Jace's parts to be a serious momentum killer, wherein the ep seem to outright stall. TBH, I liked the previous installment better, and still consider it the best so far. Favoring the odd ones (first & third), over the even ones (second & fourth), it seems. Not sure if there's anything to that, just an observation.
