Overall, it was an interesting pilot and the scenes of chaos at the beginning were really good. HOWEVER, there were some things that just left me shaking my head a little bit.
1. I don't buy that the FBI agent and his doctor wife casually went home at the end of the day. The scenes early in the day were of widespread destruction, panic, and looting. The doctor wife isn't going anywhere because the hospital is going to be absolutely FLOODED with patients, not "Oh we've got an injured boy here, everybody move! Oh wait, he's better no, guess I'll clock out". The FBI agent would most likely be spending the rest of the night with the other agents trying to help the local police get the city under control again.
2. Once the FBI agent gets to the FBI buildings it's like everything's okay now, no more trouble in the city, we're just trying to figure out why this happened now.
