Although over the top, and more than a bit wet, I think it says something about a film when it could be seen as a variant on Richard Matheson’s classic horror novel I Am Legend (1954). At what point is the protagonist just flat out murdering people? Obviously these are bad people being killed, the film takes great lengths to show us how violent, nasty and foreign they are, but ‘does anyone remember when that guy who used to work here executed those violent, nasty, foreign guys?’ is a weird and worrying question no matter which way you look at it.
Denzel does most of his ‘equalizing’ dressed like your dad at a relative’s anniversary party, it’s very flat and takes about 30 minutes longer than needed. A couple of brief scenes with Bill Pullman and Melissa Leo are worth their weight in gold.
