goof
To start, I only watched this movie because I live in St. Louis. In fact, I live just a few blocks south of Downtown so it was cool to see local landmarks like the Soldier's Memorial. Had it been set anywhere else in the world, the premise would have turned me away.
Anyway, I'm sure it was full of goofs, but the one I noticed most blatently was when Judd Nelson's daughter was on her cell trying to reach him. Her mother was driving on an overpass, and the daughter said something to the effect of "nothing's working". Even though traffic was supposedly gridlocked, you could clearly see interstate traffic flowing just fine below them. Like I said, I'm sure it's just one of many.
