Nine Bodies in a Mexican Morgue

While this series seems interesting thus far, there are some obvious flaws. First, it's a WhoDunnit with the climax already known... Out of 10 peeps, 9 people will be killed by one of them. So we just watch to see which one of them gets picked off next . There are clues if you haven't noticed as to who the ultimate culprit is / or isn't 1. Mexican authorities rule, one of them has no face ... ahh, is he the guy with the mask? So we can rule him out as a suspect... Fat Lady, no way , I could go on and on however that may be construed as a spoiler. . . Now the good doctor, well he's your guy. Why? A. he never mentioned the symptoms of the pilot dying from asphyxiation. B. when the Fat Lady did, he never concurred or disputed it . Why not? Maybe he's number 10?
