It is an interesting idea.

For me, somewhat older with iffy eyesight it is hard to use. The fonts are really small. The map could use more real estate on the screen. Right now it sits inside a container that only uses a portion of the screen.

What is confusing is why I see science fiction movies depicting recent history periods but not movies made in the period this SF movies claim to show. E.g. why include Resident Evil on Alcatraz island, but not Dirty Harry (the 2nd)? Time period movies such as Dirty Harry are precious time capsules of what San Francisco and Marin looked like at the time.
