Plot hole: This series depicts Dexter and Harry working together at Miami Metro. However, the original series established that Harry died before Dexter ever started working at Miami Metro.
Factual error: When Gio is driving Deb and she is about to dial the car phone, they drive past a fleet of rental shared Citi Bikes. Shared bikes wouldn't be a thing until the late 90s, and Citi Bike itself only began in 2013. (00:42:20)
Factual error: When Debbie Harry's "I Want That Man" is playing, just before Deb is shown being dropped off at school by Gio, an overhead shot is shown of basketball courts under a flyover. You can see modern cars parked under the flyover: at least 20 years more modern than in 1991 when the show is set. (00:06:57)
And in the Beginning... - S1-E1
Factual error: The show is set in 1991, and Dexter walks past a Lehman Brothers stall at the jobs fair. The problem is that the stall and the marketing materials on it have the modern-day Lehman Brothers logo and branding. Back in 1991, the bank was called Shearson Lehman Brothers and had a completely different logo and colour scheme. It was only spun off into Lehman Brothers in 1994. (00:10:03)
