One minor detail that I think was cool is that they highlighted the then rift between analysts and Special Agents at the time in the FBI. Analysts were treated as third class citizens and weren't allowed to do much hands on stuff at all, and were paid less. Point being made during the scene with Gunn and Wendy, when he told her to stay put and let Agents go out and do the field interviews. It's really only been in the past 10 years or so that analysts have been more accepted and 'mixed' with the Special Agents. The initial few weeks at the FBI academy are integrated these days. But even now, even during the application process, analysts have to pay for their own travel and lodging, whilst SA candidates are reimbursed.
