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.
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)
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)
