(at around 10 mins) On an IQ scale, "100" represents the average intelligence, with scores higher than that being above average, and less than that being below average. Despite this, the film charts the decline of "average intelligence" with an IQ chart starting at 110 and dropping well below 100. This makes no sense as 100 always represents the "average intelligence". Even if it was supposed to be considered comparative, the chart should start at 100, not 110.

While Joe is depicted as the most intelligent man alive in the year 2505, the vehicles, machines, and technology shown, while far from advanced, would require skills and intelligence far beyond that of Joe's to design and construct. In fact, depicted falling buildings show the civilization is in crisis and living from the remaining buildings and technology from the past. In the same way, those machines were built centuries ago and just still working, or maybe there were remaining factories that were 100% autonomous building them.

Throughout the character listing, Joe Bauer is listed as "officer" or "private". He is actually a Corporal.
(at around 19 mins) Just after he has awaken on 2505, Joe is seen watching a movie at the cinema, however, at that moment he could not have had any money to pay for the ticket.
