I love how Last Ship alternates between "there's no one left in the world" and "a vaccine will save the world." Sometimes this happens in the same sentence.
"See -- so anyone who gets the virus will die within 48 hours. And that's why it's so important for us to find the vaccine." Um...six months after the outbreak, one month after your last contact with any organized government or group.
But then we see infected people -- like two episodes ago -- who seem to be existing as sort of lepers and outcasts. Which isn't how any superflu would ever work, but okay...
I also like that the Russian ship receives catastrophic damage every time we encounter it, and yet they seem to be just fine when next we see them.
Oh, and I love that patient zero's experiment makes no sense at all, killed "four billion people," and he's angry when people call him a monster. His argument is, for the most part, I'm not the monster, you're the monster!
Meanwhile, on The Strain... Flashbacks to concentration camps are much more exciting than the actual present day story, which is about how people don't believe in vampires even when they're attacked by them.
