I get the mediation in the beginning was supposed to establish the main character as someone both devoted to his family but obsessed with his job, but damn, it was like ten minutes long and completely killed whatever momentum they were trying to build.
Samwise kills everyone in the city because of a plot straight out of the worst of 24. And the crate of death was clearly visible from outside the van and the driver is clearly a tattooed gangbanger who was clearly going for his gun, but the SWAT guys do nothing.
Two-hundred fatalities and ONE CORONER?! Ummm...no, that would not happen. And no, the throw away line from the lead about avoiding press leaks by keeping city MEs away from the bodies doesn't cover it. Not to mention the redshirt CDC ME doesn't understand the concept of a mystery contagion that has killed hundreds might need more than thin gloves for protection? Yeah, go ahead and pick up the clearly EGG-filled heart that's flopping around and look at it. Brilliant.
The old man who clearly knows things he couldn't reasonably know unless what he is saying is valid is arrested because of ... what? Being old and creepy? His sword cane? Sigh. Yet the parent who assaulted a federal agent on national tv isn't arrested. Right.
And finally, they establish that this "infection" that raises the dead and is transmitted by worms spreads like the fucking plague. In a little over three hours 200+ people have been infected and resurrected and then all of them somehow escape from the police cordon along with a 500lb crate full of more worms. The story is already over: everyone in New York City would be dead, dying or prey in days. It would be impossible to stop the spread of those worms even without the living dead vectors.
PS - What was up with the tower chief getting his head crushed by "Dracula"? He makes a call to Berlin and conveniently speaks German, because that makes sense, and Drac takes the time to lure, drain and pulverize him because...horror? Like no one else is going to think to call the flight's origin point?
Oh, and thanks for spoiling every single creepy and/or shock moment in the previews. Bravo.
