Revolution (2012)

2 mistakes

Memorial Day - S2-E21

Factual error: When the presidents are coming together, there are pictures being taken with flash photography, which would not be possible in a world without electricity.

The Plague Dogs - S1-E4

Factual error: In the flashback at the beginning of the episode where Maggie remembers the last time she talked to her children. She getting ready to go out for the evening in Seattle (and it's dark outside) while on a video call with her children in England, telling them that it's late and time for them to go to bed. Since Seattle is 8 hours behind London, and it's dark/evening there, her very young children's bed time must be 2am at the earliest.
