Braindead (CBS)-"Braindead" has a strong enough premise has enough thunder out of the gate to get you past the slow expositional burn of the first few episodes that typically sees viewers drop out when their attention spans are tested the most. After that, the show fails to maintain a sense of escalating tension. Still it's watchable enough that I made it to the end with a sense of relative satisfaction.
As far as I can remember, there's little detail as to why this hotel manager is so insanely good at every facet of espionage other than that he used to be in the army. He's just really good and that's pretty much all you need to know.
